Notes:
The compounds trans-NPCl2-n(NMe2)n(NSOPh)2(n=0-2iNPCl2-n NMe2)n (NSOPh)2 (n=0-2) and N2P2Cl4-nl4-n(NMe2)nNSOP2P2Cl4-n(NMe2)nNSOPh(n=0-4), were prepared from their chloro-precursors. The substitution follows a completely non-geminal pathway, and all possible isomers are formed. The observed relative abundance of these isomers shows that the phenyl group exhibits a strong directing effect on the incoming amine. The 1H, 31P and 13C NMR spectra of the most abundant isomers are reported. 2J(CP) couplings within the PNMe2 grouping are affected by the number of substituents at the phosphorus atom. Almost linear relationships exist between the degree of substitution and the chemical shift of C-1 and C-4 of the phenyl groups. The effect of substitution on the 13C chemical shifts of these groups is ascribed to inductive effects.
