Copper-mediated reaction of oxazirconacyclopentenes with dichlorophenylphosphine: a new pathway for the formation of 1,2-oxaphosphole derivatives†
Abstract
Copper-mediated reaction of oxazirconacyclopentenes with dichlorophenylphosphine afforded 2,5-dihydro-1,2-oxaphosphole in high yields, in which the reaction was performed conveniently in one-pot from an alkyne, carbonyl compound and dichlorophosphine.
