苯基次甲基三苯基膦烷 | triphenyl(phenylmethylene)phosphorane | 16721-45-2 | C25H21P | 352.415 |
Triphenylphosphonium 1-trimethylsilylbenzylides 1 react with the bis(dichlorophosphino)- substituted ylide 2 both at their 1- and ortho-position to yield 1,3-diphosphatetraline derivatives 4 containing two ylide and PCI units each as alternating ring members. The two PCI groups differ decisively in their spontaneous dissociation in a polar medium, as well as in their oxidation by elemental sulfur. With gallium trichloride dicationic 1,3-diphosphanaphthalenes (1,3-benzodiphosphinines) are formed, in which both phosphorus ring members achieve twocoordination and which represent a novel π10 system
