Bermuda triangle: The first molecule containing a cyclic three-membered Sn[BOND]C[BOND]P ring has been synthesized and characterized. This SnII[BOND]P Lewis pair reacts at room temperature with alkynes and pentene to give the five-membered cyclic addition products. In the case of pentene, this reaction is reversible at room temperature. Trip=2,4,6-iPr3C6H2.
