In our previous paper, 1) we reported that the cycloaddition reaction of tropothione (cycloheptatrienethione) (I) with some dienophrles gave a 1,8-cycle. adduct or its unusual rearrangement product by the rare [a8s+r2s] type of reaction, in contrast with tropones, as well known, formed normally 1,4-
PSEODOAROMATIC sulphur compounds which we have studied by means of the eimple MO-LCAO method can be divided into four groups according to the parent substances from which they can be formally derived by the substitution of the -CH=CH-group by a sulphur atom. The compounds under consideration are ana
By means of the electron-topologic approach, combining the methods of the pattern recognition theory and the electron and geometric description of the molecular systems under consideration, the totality of 52 sulphur-containing organic compounds is investigated. The electron-topologic activity fragm
