Patent ID: 7115762

Claim:
A palladacycle catalyst of formula (I) in which each is a single bond or a double bond, provided that if one is a double bond, its neighboring is not a double bond; each of X and Z, independently, is —P(R′)—, —S—, —N(R′)—, or —N═, in which R′ is alkyl, aryl, cyclyl, heteroaryl, or heterocyclyl; each of Y 1 and Y 2 , independently, is an anion of an organic or inorganic acid; each of X 1 , X 2 , X 3 , Z 1 , Z 2 , and Z 3 , independently, is —C═, —CR″—, in which R″ is H, alkyl, aryl, cyclyl, heteroaryl, or heterocyclyl; and each of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 , independently, is H, alkyl, aryl, cyclyl, heteroaryl, or heterocyclyl, or R 1 , X, X 1 , and R 2 , together form a 3–8 membered ring, or R 2 , X 1 , X 2 , and R 3 , together form a 3–8 membered ring, or R 3 , X 2 , X 3 , and R 4 , together form a 3–8 membered ring, or R 5 , Z, Z 1 , and R 6 , together form a 3–8 membered ring, or R 6 , Z 1 , Z 2 , and R 7 , together form a 3–8 membered ring, or R 7 , Z 2 , Z 3 , and R 8 , together form a 3–8 membered ring; wherein at least one of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 , or the ring formed from R 1 , X, X 1 , and R 2 , or the ring formed from R 2 , X 1 , X 2 , and R 3 , or the ring formed from R 3 , X 2 , X 3 , and R 4 , or the ring formed from R 5 , Z, Z 1 , and R 6 , or the ring formed from R 6 , Z 1 , Z 2 , and R 7 , or the ring formed from R 7 , Z 2 , Z 3 , and R 8 is connected to a first polymer.
