Manganese-catalyzed synthesis of hydantoin derivatives from terminal alkynes and isocyanates
Hydantoin derivatives were obtained by the reactions of terminal alkynes with isocyanates in the presence of a catalytic amount of a manganese complex, MnBr(CO)(5). This reaction also proceeded using a rhenium complex, Re-2(CO)(10), or an iron complex, Fe(CO)(5), as a catalyst.
