Novel preparation of 1,3,5-thiadiazine derivatives by cyclocondensation of carbon disulphide with dialkylcyanamides under high pressure
Abstract
At 500 MPa, 1 mol. equiv. of carbon disulphide condenses with 3 mol. equiv. of dialkylcyanamide to afford 2,6-bis(dialkylamino)-4-dialkylthiocarbamoylimino-1,3,5-thiadiazine, the structure of which was determined by X-ray crystallography.
