Abstract

This invention concerns a new family of phosphorus-containing compounds containing a moiety JQA-- in which: A is absent or is --O--, --S-- or --NR.sup.2--; Q is absent or (if A is --O--, --S-- or --NR.sup.2--) Q may be --V--, --OV--, --SV--, or --NR.sup.2V--, 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.sup.2VA; ##STR00001## K is O or S; each occurrence of Y is independently --O--, --S--, --NR.sup.2--, or a bond linking a R.sup.5 moiety to P; each occurrence of R.sup.2 and R.sup.5 is independently an aliphatic, heteroaliphatic, aryl, or heteroaryl moiety, or H; and each occurrence of R.sup.6 is independently --PK(YR.sup.5)(YR.sup.5), --SO.sub.2(YR.sup.5) or --C(O)(YR.sup.5); so long as any R.sup.2, or R.sup.5 moiety linked directly to P is not H; wherein two R.sup.2, R.sup.5 and/or R.sup.6 moieties may be chemically linked to one another to form a ring; each occurrence of G is independently --O--, --S--, --NR.sup.2-- or (M).sub.x; each occurrence of M is independently a substituted or unsubstituted methylene moiety, and any M M' moiety may be saturated or unsaturated; each occurrence of x is independently an integer from 1 6; and the other variables are as defined herein.
