“…Catalytic activity in the reaction was found for rhodium [1][2][3], ruthenium [4][5][6], palladium [7][8][9][10] and selenium [11][12][13] compounds. The palladium catalysts, on account of their relatively lower price and a high activity and selectivity, arouse greater interest.…”

“…However, this mechanism has not as yet been conclusively learnt. One of the suggested mechanisms is a direct carbonylation of nitrobenzene to carbamate by an intermediate nitrene stage [7,10]. Alternatively, Leconte et al [28] isolated a palladocyclic intermediate from the reaction of nitrobenzene with CO and proposed this as an intermediate.…”

“…One of the suggested mechanisms is a direct carbonylation of nitrobenzene to carbamate by an intermediate nitrene stage [30]. Some authors agree that this reaction proceeds via an intermediate stage of aniline formation, which is subsequently directly carbonylated to carbamate [30,31]. An alternative mechanism postulated involves aniline carbonylation to isocyanate, which immediately reacts with the excess aniline to afford diphenylurea [32,33].…”

The effect of the components of the PdCl2/Fe/I2/Py catalytic system on nitrobenzene carbonylation to ethyl N-phenylcarbamate

Abstract:The PdCl 2 /Fe/I 2 /Py catalytic system (Py -pyridine), reported to be highly active in the reaction of nitrobenzene carbonylation to ethyl phenylcarbamate was studied. The present paper describes the role of catalyst components and its effect on the activity and selectivity of the catalyst. The increase in the amount of PdCl 2 in the system while retaining a constant level of the other catalyst components, results in the increase of both carbamate and aniline yields. The increase in the amount of iron while retaining the other components constant, initially causes an increase in the carbamate yield; however, at Fe : Pd ratios higher than 36, the carbamate yield remains constant. The change in the amount of iron has no effect on the amount of aniline formed in the system. An increase in the amount of iodine in the system while retaining the other components constant, results in a decrease in carbamate yield and a considerable increase in the aniline yield of the reaction products.
