Synthesis and Structure of a Cationic Platinum Borylene Complex

摘要

Terminal borylene complexes with two-coordinate boron atoms were first reported in 1998 and have since attracted significant interest owing to their close relationship to ubiquitous carbonyl complexes and, moreover, because of their propensity to serve as unique sources for elusive borylene units (B-R) under ambient conditions. The latter has allowed for the versatile and synthetically very useful borylene transfer to various transition-metal fragments or even to unsaturated organic substrates.
