资源简介：
The propargylic salt [Ph3PCH2CCH]PF6 ([1]PF6) undergoes a
facile rearrangement to the allenyl isomer [Ph3PCHCCH2]PF6 ([2]PF6) upon coordination to rhodium and iridium. The η2-allenylphosphonium salts [IrX(η2-CH2CCHPPh3)(CO)(PPh3)2]PF6 (X = Cl, [4]PF6; X = Br, [5]PF6) and [RhCl(η2-CH2CCHPPh3)(PPh3)2]PF6 ([7]PF6) have been synthesized and characterized, including
X-ray crystallographic analyses. In the case of rhodium, it was found
that [7]PF6 was also formed by
the reaction of the α-alkynylphosphonium salt [Ph3PCCCH3]PF6 ([3]PF6) with [RhCl(PPh3)3]. The
complex [RhCl(CO)(PPh3)2] was found to catalyze
the isomerization of [1]+ to [2]+.
