A variety of synthetic approaches to neutral terminal borylene complexes [LxM= BR](R= N (SiMe3), Si (SiMe3)) has been developed over the past years on the basis of salt elimination [1] or transmetalation reactions.[2] Recently, we also demonstrated that homo-[3] and heterodinuclear [4] bridged borylene species are susceptible to cleavage reactions, thus yielding in the former case the first terminal alkyl borylene species [(η5-C5H5)(OC) 2Mn= ...
