Synthesis of 5- and 6-Substituted 2-Methylbenzothiazoles under Conditions of Metal Complex Catalysis

Methods are proposed for preparation of 5- and 6-substituted 2-methylbenzothiazoles by reactions of organozinc and organotin compounds with 5- and 6-bromo-2-methylbenzothiazoles, catalyzed by palladium complexes. The reactions of organozinc compounds with 5(6)-bromo-2-methylbenzothiazoles occur in THF at 20°C in the presence of PdCl2(dppf), and those of organotin compounds are carried out in DMF, aqueous DMF, or water at 40-100°C in the presence of PdCl2, Pd(OAc)2, or PdCl2(PPh3)2.

THE SYNTHESIS OF o-NITROBENZENETHIOLS: AN ADVANTAGEOUS NUCLEOPHILIC DISPLACEMENT ON o-CHLORONITROBENZENES

Reaction of substituted o-chloronitrobenzenes with sodium sulphide in DMSO occurs rapidly and gives the corresponding o-nitrobenzenethiols, following a convenient one-step pathway.Better yields are obtained when stoicheiometric amounts of sulphur, dissolved in a little carbon disulphide, are added in the presence of ethyl methyl ketone as solvent.
