Microwave-assisted decarbonylation reactions were investigated using a palladium catalyst. A large number of aldehydes can be decarbonylated efficiently with lower catalyst loadings and under shorter reaction times compared to conventional heating. A successful decarbonylation led to the synthesis of natural product eulatachromene in three steps starting from easily available materials.
A facile decarbonylation reaction of aldehydes has been developed by employing Pd(OAc)2. A wide variety of substrates are decarbonylated, without using any exogenous ligand for palladium as well as CO-scavenger.

A general method for selective dehydroxymethylation has been discovered by using widely available Pd(OAc)(2). The present study offers a new synthetic strategy for the regioselective functionalization by employing the steric, electronic and coordinating nature of the hydroxymethyl (-CH(2)OH) group temporarily.
