Claim:
A diazaphosphacycle, comprising a compound having the formula III and salts of the compound wherein R 1 is selected from the group consisting of substituted and unsubstituted aryl groups, substituted and unsubstituted alkyl groups, substituted and unsubstituted alkenyl groups, substituted and unsubstituted cycloalkyl groups, and substituted and unsubstituted ferrocenyl groups; R 2 and R 3 are independently selected from the group consisting of substituted and unsubstituted aryl groups, substituted and unsubstituted alkyl groups, substituted and unsubstituted cycloalkyl groups, substituted and unsubstituted heterocyclyl groups, and substituted and unsubstituted ferrocenyl groups; R 4 is selected from the group consisting of —H, substituted and unsubstituted alkyl groups, substituted and unsubstituted cycloalkyl groups, substituted and unsubstituted aryl groups, trialkylsilyl groups, triarylsilyl groups, alkyldiarylsilyl groups, dialkylarylsilyl groups, —C(═O)—R 6 groups, —S(═O) 2 —R 6 groups, —P(═O)R 6 R 7 groups, and —C(═NR 6 )—R 7 groups; R 5 is selected from the group consisting of —H, substituted and unsubstituted alkyl groups, substituted and unsubstituted cycloalkyl groups, substituted and unsubstituted aryl groups, trialkylsilyl groups, triarylsilyl groups, alkyldiarylsilyl groups, dialkylarylsilyl groups, —C(═O)—R 7 groups, —S(═O) 2 —R 6 groups, —P(═O)R 6 R 7 groups, and —C(═NR 6 )—R 7 groups; R 6 is selected from the group consisting of substituted and unsubstituted alkyl groups, substituted and unsubstituted alkenyl groups, substituted and unsubstituted cycloalkyl groups, substituted and unsubstituted aryl groups, —OH groups, substituted and unsubstituted alkoxy groups, substituted and unsubstituted aryloxy groups, —NH(alkyl) groups, —NH(aryl) groups, —N(aryl) 2 groups, —N(alkyl) 2 groups, —N(alkyl)(aryl) groups, —S-alkyl groups, and S-aryl groups; R 7 is selected from the group consisting of substituted and unsubstituted alkyl groups, substituted and unsubstituted alkenyl groups, substituted and unsubstituted cycloalkyl groups, substituted and unsubstituted aryl groups, —OH groups, substituted and unsubstituted alkoxy groups, substituted and unsubstituted aryloxy groups, —NH(alkyl) groups, —NH(aryl) groups, —N(aryl) 2 groups, —N(alkyl) 2 groups, —N(alkyl)(aryl) groups, —S-alkyl groups, and S-aryl groups; R 6 and R 7 may be part of the same alkyl group, alkenyl group, or aryl group such that R 4 and R 5 together with the two nitrogen atoms of the diazaphosphacycle form a ring; and Y is a linking group selected from the group consisting of substituted and unsubstituted cycloalkyl groups, substituted and unsubstituted aryl groups, substituted and unsubstituted alkenyl groups, silyl groups, substituted alkyl groups, and groups having the formula —(CH 2 ) n — wherein n is selected from the group consisting of 0, 1, 2, and 3.
