The addition of phosphines to the manganese allenylidene complexes Cp(CO)2MnCCC(Ph)R (R = H, Ph) proceeds selectively at the C α atom to result in the α-phosphonioallenyl complexes Cp(CO)2Mn--C(+PR3 1)CC(Ph)R. The protonation of the latter affords the η2-(1,2)-phosphonioallenes Cp(CO)2Mn{η 2-(1,2)-HC(+PR31)CC(Ph)R}, rather than the phosphoniovinylcarbenes Cp(CO)2MnC(+PR 31)-HCC(Ph)R. All complexes obtained are stereochemically rigid and do not isomerize into the η2-(2,3)-phosphonioallene isomers.
