Graphical Abstract
Treatment of terminal and internal alkynes with diphenylphosphane in the presence of catalytic amounts of a base and cobalt(II) acetylacetonate affords, with perfect and universal syn selectivity, the (E)-alkenyldiphenylphosphane derivatives in good yield (see scheme, acac=acetylacetonate).
