Abstract

SiCSi to pick up a metal: A bis(silylene) SiCSi pincerlike arene 1 (see scheme) has been synthesized through salt metathesis reaction of the dilithium salt of 2,4-di-tert-butyl-resorcinolate with the respective chloro silylene precursor [LSiCl]. Remarkably, 1 reacts with Pd(PPh3)4 in a molar ratio of 2:1 under loss of all phosphine ligands to give the pincer complex 2.
