This invention concerns a new family of phosphorus-containing compounds containing a moiety JQA- in which: n A is absent or is —O—, —S— or —NR 2 —; n Q is absent or (if A is —O—, —S— or —NR 2 —) Q may be —V—, —OV—, —SV—, or —NR 2 V—, where V is an aliphatic, heteroaliphatic, aryl, or heteroaryl moiety, such that J is linked to the cyclohexyl ring directly, through A or through VA, OVA, SVA or NR 2 VA; n n n K is O or S; n each occurrence of Y is independently —O—, —S—, —NR 2 —, or a bond linking a R 5 moiety to P; n each occurrence of R and R is independently an aliphatic, heteroaliphatic, aryl, or heteroaryl moiety, or H; and n each occurrence of R 6 is independently —PK(YR 5 )(YR 5 ), —SO 2 (YR 5 ) or —C(O)(YR 5 ); so long as any R or R 5 moiety linked directly to P is not H; n wherein two R 2 , R 5 and/or R 6 moieties may be chemically linked to one another to form a ring; n each occurrence of G is independently —O—, —S—, —NR 2 — or (M) x ; n each occurrence of M is independently a substituted or unsubstituted methylene moiety, and any M-M′ moiety may be saturated or unsaturated; n each occurrence of x is independently an integer from 1-6; and the other variables are as defined herein. |
