文摘

Photoirradiation of a triruthenium alkyne complex containing a 渭₃-borylene ligand, {Cp*Ru(渭-H)}₃(渭₃-畏²()-PhCCH)(渭₃-BH) (Cp* = 畏⁵-C₅Me₅), was examined; whereas a perpendicularly coordinated alkyne complex was obtained by the irradiation with UV light (313 nm), a trimetallic complex containing a three-membered 渭₃-畏³-BC₂ ring was preferentially formed as a result of intramolecular borylene transfer by the irradiation with visible light (436 nm).
