Siloles, substituted, formation

Alkoxy-substituted highly coordinate Si-heterocycles 89YGK831. Siloles, germoles, stannoles, plumboles, formation of ionic species and coordination compounds 90CRV265. 

Rearrangements of [4 - - 2] adducts of siloles and dimethyl acetylenedicarboxylate have been extensively studied for C-phenylated siloles and, more recently, for C-methylated siloles. However, the previously described decomposition pathway with silylene extrusion and formation of a substituted dimethyl phthalate is also observed . An iron-substituted silylene [Cp(CO)2FeSiMe] has been generated by using this method. ... 

Intramolecular Reaction Pattern Formation of a-Lithio Siloles from Silyl-Substituted Di-lithio Reagents via E/Z Isomerization Followed by Nucleopbilic Attack... 

Formation of Pyridines, Pyrroles, A -Bipyrrolines, Siloles, and (Z, Z)-Dienylsilanes Remarkable E ect of Substitution Patterns on the Butadienyl Skeletons... 

All these results revealed that the substitution patterns of di-lithio reagents and the nature of nitriles played key roles in the formation of pyridines, cyclopentadie-nylamine, tricyclic A -bipyrrolines, siloles, and (Z,Z)-dienylsilanes.
