- W1980115701 abstract "The phosphorus hydrazide PhP(S)(NMeNH2)21 reacted with the azido functionalized aldehyde 4-N3C6F4CHO to give a mixture of Schiff-base adducts with one or two perfluoroaryl azido substituents on 1. However, the reaction with R′CHO (R = 4-O2NC6H4, 3-O2NC6H4 or 2,4-Me2C6H3) resulted in a considerable selectivity of incorporating one aromatic substituent in the terminal hydrazide unit of 1via Schiff-base coupling to produce PhP(S)(NMeNH2)(NMeNCHR′)(R′= 4-O2NC6H43, 3-O2NC6H44 or 2,4-Me2C6H35). These mono-Schiff-base adducts 3–5 undergo further Schiff-base coupling with azidotetrafluorobenzaldehyde to produce the azido-functionalized phosphorus hydrazides PhP(S)-(NMeNCHC6F4N3)(NMeNCHR′)(R′= 4-O2NC6H47, 3-O2NC6H48 or 2,4-Me2C6H39). The ligating properties of the representative phosphorus hydrazides 2 and 9 with palladium (II) were investigated. The crystal structure of the complex [PdCl2{PhP(S)(NMeNH2)(NMeNCHC6F4N3-4)}] reveals that the palladium(II) is bound in a chelating cis arrangement to the phosphorus chalcogenide and the hydrazine nitrogen via a five-membered metallacyclic framework: monoclinic, space group P21/n, a= 7.826(10), b= 18.051 (20), c= 18.330(3)Å, β= 98.196(7)°, Z= 4, R= 0.038 and R′= 0.053." @default.
