摘要
The homolytic methylation of napthoquinone to obtain menadione has been investigated by three sources of methyl radical: t-BuOOH, DMSO and H2O2, acetone and H2O2. Moreover the homolytic alkylation of napthoquinone and 2-methylnapthoquinone has been investigated by using alkyl iodides as sources of alkyl radicals.
