摘要：
The present invention provides microwave assisted rapid and economical process for the preparation of substituted phenylaldehydes from trans and cis-phenylpropene, a commercial utilization of toxic cis-isomer of the general formula (I) using meta-periodate and osmium tetraoxide (catalytic amount) as an efficient oxidizing agent in the presence of catalyst namely amberlite IRA-410 and quaternary ammonium salt.
