Conclusions
-
1.
It has been established that the heteronuclear cluster CpMnOs3(H)(CH=CHPh)(CO)12, which forms when Cp(CO)2Mn=C=CHPh reacts with H2Os3(CO)10, readily dissociates in solutions with the elimination of an Mn-containing fragment and the formation of trinuclear osmium clusters with bridging vinyl, acetylenic, and vinylidene ligands.
-
2.
The occurrence of the following processes with the participation of the phenylvinylidene ligand in the coordination sphere of several metal atoms has been demonstrated: hydrogenation with the formation of a phenylvinyl group and isomerization to phenylacetylene.
-
3.
The transfer of a vinylidene ligand from a mononuclear system to a metallocycle has been realized for the first time.
