An efficient, convenient and novel method for the selective mono N-arylation of primary O-alkyl thiocarbamates and primary O-alkyl carbamates with aryl halides and arylboronic acids in the presence of a recyclable magnetic Cu(ii) nanocatalyst is described. A variety of mono N-arylated O-alkyl thiocarbamates and O-alkyl carbamates were prepared in good to excellent yields with a broad range of aryl coupling partners. The magnetic nanocatalyst can be easily recovered with an external magnetic field and reused at least five times without noticeable leaching or loss of its catalytic activity. This cost-effective and eco-friendly methodology has some other advantages, such as easy preparation of the catalyst, simple workup procedure, and easy purification, which makes this protocol interesting for the users in various fields of pharmacology and biotechnology systems.

The photochemistry of O-allyl and O-but-3-enyl thiocarbamates has been studied.Photolysis of benzene solutions of O-allyl N-phenylthiocarbamates gave S-allyl N-phenylthiocarbamates.The 1,3-allyl migration from the oxygen to the sulfur involves a concerted process.The same type of 1,3-migration took place in the conversion of O-benzyl N-phenylthiocarbamate into S-benzyl N-phenylthiocarbamate.Irradiation of O-but-3-enylthiocarbamates produced iminooxolanes via aminothietane intermediates.In the case of O-but-3-enyl N-benzoyl-N-phenylthiocarbamates, 3-(benzoylmethyl)-2-phenyliminooxolanes were obtained via a ring opening of the aminothietanes involving a 1,5-benzoyl shift.
AN ADVANTAGEOUS SYNTHESIS OF S-(2-PROPENYL) N-ACYLMONOTHIOCARBAMATES BY -SIGMATROPIC REARRANGEMENT OF O-(2-PROPENYL) N-ACYLMONOTHIOCARBAMATES

Reaction of acetyl, benzoyl, 2-chlorobenzoyl, 3-phenylpropenoyl, 2-naphthoyl, and 3-chloro-2-benzothienocarbonyl isothiocyanate with 2-propen-1-ol afforded the corresponding O-(2-propenyl) N-acylmonothiocarbamates which underwent -sigmatropic rear
