using reducing agents such as sncl 2 and conc hcl or h 2 pd catalyst the process of the present invention is described herein with reference to examples which are illustrative only and should not be construed to limit the scope of the present invention in any manner the palladacycles formula 7 are synthesized for the first time in our laboratory and successfully used for the suzuki type biaryl formation reaction two necked 25 ml rb flask was charged with pdcl 2 0 177 g 1 mmol licl 0 100 g 2 4 mmol and meoh 2 ml the resulting reaction mixture was stirred under argon atmosphere at 25 u00b0 c for 2 5 h then to the same reaction was added naoac 0 123 g 1 5 mmol and a solution of the corresponding sulfilimine formula 6 0 293 g 1 mmol in meoh 2 ml sulfilimine was prepared by following published procedure sharpless et al j org chem 2001 66 594 599 the resulting reaction mixture was stirred at 25 u00b0 c for 72 h then distilled water 6 ml was added to it and the solid was filtered on sintered funnel washed with water and dried under reduced pressure 5 mm for 3 h to afford palladacycle formula 7 where in r h and r1 me as brown colored solid yield 66 mp 135 141 u00b0 c decomp preparation of palladacycle where in r h and r1 ch ch 3 two.
