Formation of a coordinated 2-aminoethylidene ligand and its rearrangement by deprotonation into a phosphinoallyl ligand containing a pyrrolidin-2-yl ring.
The activation of 1,1-diphenyl-2-propyn-1-ol by the metallic fragment [(eta (5)-C 5Me 5)Ru(dippae)] (+) {dippae = 1,2-bis[(diisopropylphosphanyl)amino]ethane}, followed by dehydration, produces a cationic complex that, by deprotonation and rearrangement, leads to a neutral complex with a phosphinoallyl ligand containing a pyrrolidin-2-yl ring.
