The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

benzene;
an org. compd. (0.01 mmol) in benzene was added to Pd-contg. compd. (0.005 mmol) in the same solvent; the soln. was heated and stirred at 60°C for 16 h; without cooling, hydrazine was added dropwise until theevolution of gas ceased; the solvent was removed in vacuo, the residue was dissolved in a min. amt. of CH2Cl2 and reprecipitated in cold ethanol; the soln. was filteredand the solid collected and dried;
