Abstract:
The present invention provides a complex of formula (1), wherein, M is palladium or nickel, R 1  and R 2  are independently organic groups having 1-20 carbon atoms, or R 1  and R 2  are linked to form a ring structure with the phosphorus atom, R 3  is selected from the group consisting of substituted and unsubstituted aryl, substituted and unsubstituted heteroaryl, and substituted and unsubstituted metallocenyl, R 4  is an organic group having 1-20 carbon atoms, n is 0, 1, 2, 3, 4 or 5, and X is an anionic ligand. The invention also provides a process for the preparation of the complex, and its use in carbon-carbon or carbon-nitrogen coupling reactions.

Claim (Index 1):
A complex of formula (1): wherein:\n M is palladium or nickel, \n R 1  and R 2  are, independently, C 1-20  straight-chain alkyl, C 1-20  branched-chain alkyl, C 3-15  cycloalkyl, C 5-20  aryl, or C 3-20  heteroaryl, or R 1  and R 2  are linked to form a ring structure with the phosphorus atom, \n R 3  is a) or b):\n a) substituted aryl, wherein the aryl is substituted with one more halide, C 2-20  alkoxy, substituted C 6-20  aryl, branched-chain (C 1-20  dialkyl)amino, C 2-15  heterocycloalkyl, or tri(halo)methyl; or \n b) substituted or unsubstituted heteroaryl; \n \n R a  is C 1-20  straight-chain alkyl, C 1-20  branched-chain alkyl, C 3-15  cycloalkyl, C 6-20  aryl, or C 5-20  heteroaryl; \n n is 0, 1, 2, 3, 4 or 5, \n X is halo; \n wherein each alkyl, alkoxy, heteroalkyl, aryl or heteroaryl is optionally substituted with one or more halo, C(halo) 3 , R a , \u2550O, \u2550S, OR a , SR a , NR a R b , \u2550NR a , \u2550N\u2014OR a , CN, SCN, NCS, NO 2 , C(O)R a , C(O)OR a , C(S)R a , C(S)OR a , S(O) 2 OH, S(O) 2 R a , S(O) 2 NR a R b , OS(O)R a , or C(O)NR a R b , wherein:\n R a  and R b  are, independently, H, C 1-20  alkyl, C 6-20  aryl, C 6-20  aryl-(C 1-20 alkyl), C 1-20  heteroalkyl, or C 6-20  heteroaryl, or together with the atom to which they are attached form a C 3-15  heterocycloalkyl; and the heteroatoms in the heteroaryl, heteroalkyl or heterocycloalkyl are sulfur, oxygen, or nitrogen.
