Alkynyl germatranes as alternative reagents for the preparation of biarylethynes
摘要:
Arylalkynyl germatranes react with aryl chlorides and triflates to give the corresponding biarylethynes in good yield. The reaction proceeds under mild conditions in the presence of a palladium phosphine catalyst and fluoride ions. (C) 2002 Elsevier Science Ltd. All rights reserved.
