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.
