A phosphino- or arsenoamidine of Formula (1) M is Phosphorus or Arsenic (P, As); X, Y, and Z can be independently selected from hydrogen, alkyl, aryl (pendant or fused), halogen, alkoxy (C1-C10), cyano, nitro, amino, alkylamino, dialkylamino, -CO2H, -CO(lower alkoxy), -CO(lower alkyl), -NCOH, -NCO(lower alkyl), NSO2(alkyl), - NSO2(aryl), hydroxy, alkyl, sulfonoxyalkyl, sulfonoxyaryl, or alkoxyalkyl; R1 is hydrogen, C1-C10 alkyl, branched alkyl or cycloalkyl; aryl, substituted aryl, heteroaryl or substituted heteroaryl where the heteroatoms may include atoms of nitrogen, oxygen, or sulfur, may be acyl, aroyl, substituted aroyl, heteroaroyl, or substituted heteroaroyl, or SO2R4 where R4 is chosen from the group alkyl, aryl, heteroaryl, substituted aryl or substituted heteroaryl groups in direct attachment, with the provisos that R2 and R3 can be the same or different and are hydrogen, aryl or heteroaryl as defined above, substituted aryl or heteroaryl as defined (with substituents as defined below), alkyl, branched alkyl, cycloalkyl, benzyl, subtituted benzyl, with substituents as defined for aryl, or R2 and R3 together may form a fused carbocyclic ring, Ring B is an imidazoline ring or a tetrahydropyrimidine ring.
