The synthesis and characterization of two new bulky N,P-monophosphaamidines (also known as C-aminophosphaalkenes) are described. These phosphorus analogues to amidines are shown to exhibit isomerism and tautomerism in solution that is characteristic tothe amidine functional group. In addition, the nature of the P=C-N system is examined using DFT techniques. Metal complexes of the title compounds with Group 6 metal carbonyls (L-M(CO)5, M=Cr,Mo,W) are also described. A new primary phosphane is reported that contains the sterically bulky, 2,6-diisoropylphenyl (Dip) group, along with mono and disilylated derivatives. Also included is the synthesis and characterization of a new bulky N,N',P-monophosphaguanidine.
