Phosphorus phthalocyanine

Phosphorus phthalocyanine was described in 1981.161 However, recent investigations point to the fact that the originally described compound did not have a phthalocyanine structure.162...

Hexacoordinated phosphorus compounds derived from phthalocyanines have been similarly prepared. Hanack investigated the reaction of metal-free phthalocyanines with POBr3 or POCI3 in presence of pyridine [98]. The corresponding dihydroxyphosphorus phthalocyanine hydroxides 60 were characterized. 

Diimines such as bpy and phen replace 2-(arylazo)pyridine ligands (aap) in [Pd(aap)Cl2] by a simple second-order process, whose detailed mechanism may depend on the nature of the incoming ligand (254). Three phthalocyanine units, each containing Zn2+, can be bonded to tetrahedral phosphorus, to give [PPh(pc-Zn)3]+. Mechanistic proposals are advanced for this novel exchange reaction in which palladium-bound phthalocyanine replaces phenyl on phosphorus (255).
