Reactions of 1,2-dihalocycloalkenes with alkali metals in presence of chlorotrimethylsilane. Reductive carbon-carbon bond cleavage in five membered homocyclic system
1,2-Dihalocyclopentenes on reaction with alkali metals and chlorotrimethylsilane in hydrocarbon or ether solvents produce silylated 1-pentynes by ring opening. Sodium metal and hydrocarbon solvents favour the cleavage most. Different mechanistic aspects are considered.

HOMOLYTIC ADDITION OF TETRAHYDROFURAN AND 1,4-DIOXANE TO TRIALKYL- AND TRIETHOXY(VINYL)SILANES
A convenient method for the initiation by oxygen of homolytic reactions of tetrahydrofuran with trimethyl-, triethyl, and triethoxy(vinyl)silane is proposed.Previously undescribed organosilicon derivatives of 1,4-dioxane and dibutyl ether were synthesized.
