Abstract
Dichlorobis(triphenylphosphine) platinum(II) shows good catalytic activity for the reductive N-carbonylation of dinitroarenes in ethanol in the presence of a Lewis acid and triethylamine. From 2,4-dinitrotoluene, diethyl 4-methyl-1,3-phenylenebiscarbamate is obtained in 50% yield at 190°C under carbon monoxide pressure of 60 kg cm−2.
