1.4 Thiazane derivatives

Dibromoethyl sulphide, like the dichloro-compound, easily reacts with primary amines, forming the corresponding thiazane derivatives (Burrows). 

Hydrogenated derivatives of the monocyclic and bicyclic oxazines and thiazines are also very well established compounds and a number are so familiar that they too have trivial names. Tetrahydro-l,4-oxazine, for example, is better known as morpholine, a name first allocated to it because of a supposed, but erroneous, relationship to the alkaloid morphine. By analogy the corresponding thiazine is called thiomorpholine or sometimes thiazane. 

Other recent papers report on u.v. spectroscopic studies of 1,5-di-substituted 2,4-dithiobiurets, isatinthiosemicarbazones, 2,4-dihydroxy-dithiobenzoic acid, thiocarbonyl difluoridethiophosgene, 3-substi-tuted 2-thioxo-4-oxo-3,4-dihydro-2H-l,3-benzoxazines, 2- and 4-thioxo-1,3-thiazanes, rhodanine and its S- and N-methyl derivatives, and co-balt(ii) and nickel(ii) complexes of N-allylthiourea. ...
