Thiophosphonic - and thiophosphinic acid esters of (I) to (VI):- R1 and R" = opt. substd. hydrocarbon residues (C1-30); R3-R8 = H, CN, F, Cl, Br or hydrocarbon residues (C1-28); R4=h when m=0 or when R3+R5 form together alkyllene or alkenylene; p and n= 0 or 1; m= a whole number and 0 or greater; R9= a hydrocarbon residue (C1-10) or:- R10, R11 and R12 = H, Cl, CN, a hydrocarbon residue (C1-8) or a monosubstd. hydrocarbon residue (C1-8); at least one of r11 and R12 is other than H when n=0 R13=alkyl (C1-6), opt. substd. aryl (C6-8), a heterocyclic residue (C2-10), acyl (C1-3) or opt. substd. benzoyl or:- at least one of R9 and R13 contains P.
