This invention relates to a new family of phosphorus-containing compounds containing a JQA- fragment in which A is absent or is —O—, —S— or —NR—; Q is absent or (if A is —O—, —S— or —NR—) Q may be —V—, —OV—, —SV— or —NRV—, where V is aliphatic, heteroaliphatic, aryl or a heteroaryl moiety such that J is linked to the cyclohexyl ring directly, via A, or via VA, OVA, SVA or NRVA; J = (I) or (II), K represents O or S; Y in each case independently represents —O—, —S—, —NR— or a bond connecting the Rc P fragment; and other variables are as defined in this document. |
