Double Phosphinylation of Propargylic Alcohols: A Novel Synthetic Route to
Derivatives. — The ruthenium-catalyzed title
06- 164 1,2-Bis(diphenylphosphino)ethane
reaction with diphenylphosphine oxide gives the corresponding 2,3-bis-(diphenylphosphinyl)-1-propenes in high yields and complete selectivity. When other terminal
alkynes such as 1-octyne, phenylacetylene, ethyl propiolate, and 4-phenyl-5-hexyn-2-one are used in place of propargylic alcohols, no reaction occurs. — (MILTON,
