The present invention provides Acyclic diaminocarbene complex of formula (I):
Wherein,
M is palladium;
X is monoanionic ligand selected from Cl, Br or I;
Where R1 is different from R2;
R1 is selected from the group consisting of alkyl or aryl, each of which have 4 to 20 carbon atoms, and may optionally contain one or more heteroatoms;
R2 is selected from the group consisting of alkyl, or aryl each of which have 4 to 20 carbon atoms, and may optionally contain one or more heteroatoms. The said palladium diamino carbine complex of the present invention are particularly useful as catalyst from Hiyama cross-coupling reaction.
