Terminal 1-halo- 1 and 1-pseudohalo-1-alkynes via bis(trimethylsilyl)peroxide (BTMSPO) promoted Umpolung transfer of Halides and pseudohalides.
摘要:
Reaction of terminal acetylenes with readily available and inexpensive copper and zinc halides and pseudo-halides and BTMSPO has been found to be an effective and general route for obtaining, in the absence of bases and under mild conditions, 1-halo- and 1-pseudohalo-1-alkynes in generally good yields.

Condensation products of several halogermanes and halosilanes with cyclohexene oxide have been identified and characterized. The opening of the oxide linkage of cyclohexene oxide has been investigated through hydrolysis of the intermediate products (cis/transcyclohexene halohydrin isomers) produced in these reactions. It is proposed that the subject condensation reactions proceed via a pentacovalent
