    摘要: An olefin polymerisation catalyst comprising:
    (I) a complex comprising a ligand of formula (I)

    coordinated (as shown) to a metal ion M; and
    (II) a cocatalyst; or the reaction product thereof;

    wherein each X which may be the same or different is NR 3 or O;
    each Y which may be the same or different is C, S, P, S=O;
    each R 1 which may be the same or different is hydrogen, an optionally substituted C 1-20 hydrocarbyl group, -CN, N(R 4 ) 2 , silyl, siloxy, -CF 3 , -SH, -C(=NR 4 )NR 4 R 4 , -NR 4 C(=O)R 4 , -NR 4 C(=NR 4 )R 4 , -NR 4 C(=NR 4 )NR 4 R 4 , -NR 4 C(=O)OR 4 , -NR 4 C(=O)NR 4 R 4 , -NR 4 S(O) 2 R 4 , -S(O) 2 NR 4 R 4 , -C(=S)NR 4 R 4 , -OC(=O)R 4 , -OC(=O)NR 4 R 4 , -OR 4 , optionally substituted heterocyclyl, or optionally substituted heteroaryl;
    each R 2 which may be the same or different is an optionally substituted C 1-20 hydrocarbyl group, halo, silyl, siloxy, nitro, -CN, N(R 4 ) 2 , -CF 3 , -SH, C(=O)R 4 , OC(=O)R 4 , C(=O)OR 4 , -OC(=O)NR 4 R 4 , -OR 4 , optionally substituted heterocyclyl, or optionally substituted heteroaryl or two R 2 groups attached to adjacent ring atoms together form an optionally substituted 5- to 8-membered fused ring;
    each R 3 which may be the same or different is hydrogen, or an optionally substituted C 1-20 hydrocarbyl group;
    each R 4 which may be the same or different is a hydrogen, an optionally substituted C 1-20 hydrocarbyl group, or two R 4 groups taken together form an optionally substituted 5- to 8-membered fused ring;
    a is 0 to 3;
    b is 1 unless the atom Y to which R 1 is attached is P wherein b is 2.
