(P)Review

Reviews in Angewandte Chemie, written by leading experts, summarize the important results of recent research on topical subjects in all branches of chemistry, point to unresolved problems, and discuss possible developments. Although review articles are generally written upon invitation of the editor, unsolicited manuscripts are also welcome provided they are in keeping with the character of the journal.

Functional Materials from Cellulose-Derived Liquid-Crystal Templates

Functional Materials from Cellulose-Derived Liquid-Crystal Templates

Out of the woods: Novel mesoporous and nanostructured materials can be generated by templating approaches based on cellulose-based liquid crystals derived from trees. This Review focuses on materials templated by cellulose nanocrystals, since their chiral nematic order allows their use in various optical applications such as optical filters, sensors, and optoelectronics.

Chemically Powered Micro- and Nanomotors

Dr. Samuel Sánchez, Dr. Lluís Soler, Jaideep Katuri

Chemically Powered Micro- and Nanomotors

Moving down in the world: Chemically powered micro- and nanomotors are small devices that are self-propelled by catalytic reactions in fluids. Remotely guided nanomotors can transport cargo to desired targets, drill into biomaterials, sense their environment, mix or pump fluids, and clean polluted water.

Terpenoid Biosynthesis Off the Beaten Track: Unconventional Cyclases and their Impact on Biomimetic Synthesis

Terpene and terpenoid cyclizations are counted among the most complex chemical reactions occurring in nature and contribute crucially to the tremendous structural diversity of this largest family of natural products. This Review outlines novel terpenoid cyclases (TCs) beyond typical class I and II TCs, and showcases how their intriguing reaction mechanisms can inspire synthetic chemistry.

Oil/Water Separation with Selective Superantiwetting/Superwetting Surface Materials

Dr. Zonglin Chu, Prof. Dr. Yujun Feng, Prof. Dr. Stefan Seeger

Oil/Water Separation with Selective Superantiwetting/Superwetting Surface Materials

Stringent segregation: Superhydrophobic/superoleophilic surfaces and underwater superoleophobic surfaces have been successfully designed, fabricated, and employed in the separation of oil/water-free mixtures and emulsions on the basis of their selective superantiwetting/superwetting properties towards water and oil. Progress, remaining problems, and future challenges in this field are discussed in this Review.

Molecular Rare-Earth-Metal Hydrides in Non-Cyclopentadienyl Environments

Dr. Waldemar Fegler, Dr. Ajay Venugopal, Dr. Mathias Kramer, Prof. Dr. Jun Okuda

Molecular Rare-Earth-Metal Hydrides in Non-Cyclopentadienyl Environments

Beyond Cp: Molecular hydrides of rare-earth metals play an important role as homogeneous catalysts and as models of solid-state interstitial hydrides. This Review provides an overview of rare-earth-metal hydride complexes(without cyclopentadienyl ligands), with emphasis on the structural motifs and the effect of cationic charges on reactivity.

Argentophilic Interactions

Prof. Dr. Hubert Schmidbaur, Dr. Annette Schier

Argentophilic Interactions

Silver likes silver: Extensive evidence has accumulated in recent years that significant bonding interactions occur between seemingly closed-shell silver(I) centers of silver compounds. This argentophilic bonding appears to determine many structural details and important physical properties of silver(I) compounds in much the same way as aurophilic bonding is ubiquitously “at work” in gold chemistry.

C[BOND]H Bond Activation by f-Block Complexes

[BOND]H Bond Activation by f-Block Complexes" title="C[BOND]H Bond Activation by f-Block Complexes" style="float: left; padding-right: 10px"/>

Potential of transition metals: Numerous known lanthanide and actinide complexes are able to selectively activate C[BOND]H bonds of organic substrates. However, the challenge of establishing a closed catalytic cycle still remains. Many f-block complexes show great potential in this important area of chemistry.

Selective Carbon–Carbon Bond Cleavage for the Stereoselective Synthesis of Acyclic Systems

Prof. Dr. Ilan Marek, Dr. Ahmad Masarwa, Dr. Pierre-Olivier Delaye, Dr. Markus Leibeling

Selective Carbon–Carbon Bond Cleavage for the Stereoselective Synthesis of Acyclic Systems

Open, sesame! The creation of new bonds has dominated the field of organic synthesis; however, selective C[BOND]C cleavage (see scheme) is an important alternative for the construction of interesting molecular frameworks. This Review examines approaches to the synthesis of challenging acyclic molecular skeletons by the regio-, diastereo-, or enantioselective cleavage of carbon–carbon bonds, with a focus on the ring opening of small rings.

Synthesis of Extended π-Systems through C–H Activation

Prof. Dr. Yasutomo Segawa, Takehisa Maekawa, Prof. Dr. Kenichiro Itami

Synthesis of Extended π-Systems through C–H Activation

By no means π in the sky! The activation of aromatic C[BOND]H bonds by a transition metal catalyst has received significant attention in the synthetic chemistry community. In recent years, rapid and site-selective extension of π-electron systems by C–H activation has emerged as an ideal methodology for preparing conjugated organic materials. This Review focuses on recently developments in this area directed toward new optoelectronic materials.
