摘要
(Chemical Equation Presented) The heat is on: In the first instance of thermal reactivity of the terminal borylenes [(OC)5M=B=N(SiMe 3)2] (M = Cr, W), the new heterodinuclear complexes [(OC)4M(μ-CO) {μ-BN(SiMe3)2}Pd(PCy 3)] (see structure; M = Cr) are synthesized. The compounds feature a semibridging borylene ligand and, by virtue of the dative Pd-B bonding interaction, represent the only examples of terminal borylene species stabilized by a transition-metal base. © 2005 Wiley-VCH Verlag GmbH & Co.
