S. Hariprasad et G. Nagendrappa, REACTIONS OF 1,2-DIHALOCYCLOALKENES WITH ALKALI-METALS IN PRESENCE OFCHLOROTRIMETHYLSILANE - REDUCTIVE CARBON-CARBON BOND-CLEAVAGE IN 5 MEMBERED HOMOCYCLIC SYSTEM, Tetrahedron, 49(16), 1993, pp. 3387-3396
1,2-Dihalocyclopentenes on reaction with alkali metals and chlorotrime
thylsilane in hydrocarbon or ether solvents produce silylated 1-pentyn
es by ring opening. Sodium metal and hydrocarbon solvents favour the c
leavage most. Different mechanistic aspects are considered.
