The present invention relates to a composition comprising a phosphacycle-containing ligating compound represented as:
wherein:
P is phosphorus; X1 is phosphorus; each of R1 and R2 is independently a substituted or
unsubstituted hydrocarbon derivative, a substituted or unsubstituted heterohydrocarbon derivative, or a substituted or unsubstituted heteroatom group having from one to 50 non-hydrogen atoms; m is 1; R1 and R2 are linked together to form a divalent moiety represented as
which together with P forms a cyclic structure (phosphacycle) containing from 3 to 10 ring atoms; each of R3 and R4 is independently hydrogen, halogen, a substituted or unsubstituted hydrocarbon derivative, a substituted or unsubstituted heterohydrocarbon derivative, or a substituted or unsubstituted heteroatom group having from one to 50 non-hydrogen atoms; R3 and R4 are optionally linked together to form a divalent moiety represented as
wherein the optional character of the linkage is depicted by a dashed connection, which together with X1 forms a cyclic structure containing from 3 to 10 ring atoms; Y is a divalent linking group [L(R5)q]p between P and
X1 containing from one to 50 non-hydrogen atoms; [L(R5)q]p is represented by:
wherein each L is independently selected from the group consisting of nitrogen; p is an integer number from 1 to 6; R5 is independently hydrogen, halogen, substituted or unsubstituted hydrocarbon derivative, substituted or unsubstituted heterohydrocarbon derivative, or a substituted or unsubstituted heteroatom group; q is 0, 1, or 2; provided that the [L]p subunit of the divalent linking group [L(R5)q]p does not comprise an amidine (N-C=N) group; further provided that in at least one phosphacycle of the phosphacycle-containing ligating compound, both atoms directly bonded to P or X1 are sp3 hybridized; still further provided that one or two phosphacycles comprising P, R1, and R2, or comprising X1, R3, and R4, contain no P-N, P-O, or P-S bonds within the ring part of the phosphacycle; two R5 groups attached to the same L atom may be optionally linked together to form a cyclic structure that contains from 3 to 10 ring atoms; from two to ten independently selected ligating compounds may be optionally linked together via their respective independently selected Y, R1, R2, R3, R4 or R5 groups to form a poly(ligating compound) species, and wherein the composition is not 8-aza -1-phosphatricylo[3.3.0.02,6]octane.
