the Wacker process for C═O bond formation in terminal olefins can be initiated by a combination of the Pd(II) and hypervalentiodinereagent, Dess–Martin periodinane to generate methyl ketones. This operationally simple and scalable method offers Markovnikov selectivity, has good functional group compatibility, and is mild and high yielding.

An efficient and environmentally benign method using Fe(III) sulfate as a terminal oxidant in the synthesis of methylketones from terminal olefins via the Wacker process is developed. The methodology offers high selectivity for a Markonikov product, shows good functional group compatibility, involves mild reaction conditions, and is operationally simple. Fe2(SO4)3 is the sole terminal oxidant in this

An efficient synthesis of methyl ketones from terminalolefinsusing PdCl2/CrO3 system mimicking the Wacker process is developed. The method shows good functional groups compatibility, no aldehyde by-products and is operationally simple. CrO3 is the sole oxidant and replaces both Cu-salts and molecularoxygen, traditionally used in this process. The method holds potential for future applications in
