Carbon monosulphide, reaction

Coordination of unbonded electron pairs may also occur with carbon monoxide (or carbon monosulphide) in association reactions in which the adduct is stabilized by collision or by the emission of radiation (26) ... 

The reaction of sodium polysulphide with dihalides containing 4-5 carbon (or carbon + oxygen) atoms in the main chain may produce monosulphidic ring structures in addition to some linear polymer. This reflects the well-known stability of five- and six-membered ring structures and is illustrated in Table 15.2 (Berenbaum, 1%2). 

Barton and his group have prepared the interesting new di-t-butyl thio-ketone (7) in high yield by reaction of carbon disulphide with the lithium salt of the corresponding ketone imine. Independently, Ohno and his co-workers have published an analogous synthesis of this non-enethiolizable thioketone (7). Aliphatic thiones and, possibly, enethiols have been obtained by reaction of arylimines with benzoic anhydride and a stream of hydrogen sulphide. Treatment of a vinyl chloride with sodium monosulphide led to the isolation of thio-dimedone (8 R = H), which has an enethiol ketone structure. Basic hydrolysis...
