摘要

Regioselective Pd0-catalyzed cross-coupling of substrates, which bear bispropargylic leaving groups with silyl-protected alkynes, has provided access to a variety of 1, 3- diethynylallenes, a new family of modules for three-dimensional acetylenic scaffolding. In enantiomerically pure form, these C-rich building blocks could provide access ą by oxidative oligomerization ą to a fascinating new class of helical oligomers and polymers with all- ...
