Phosphonio-substituierte 1,3-Diphosphanaph thaline aus der a,o-Kondensation von Phosphonium-benzyliden / Phosphonio-Substituted 1,3-Diphosphanaphthalenes from the α.o-Condensation of Phosphonium-benzylides

Phosphonio-substituierte 1,3-Diphosphanaph thaline aus der a,o-Kondensation von... Abstract 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 http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Zeitschrift für Naturforschung B de Gruyter
