Article abstract of DOI:10.1002/ardp.2503241204

Reactions of 1,2,4-dithiazolidine-3,5-diylidene-bis(o-benzoquinone-met hid) 3 with alkyl and substituted benzyl or phenacyl halides yield 1,2,4-dithiazol-3-ylidene-quinone-methides 4a-4i. Mass spectral fragmentations of 4a, 4c, and 4f are discussed. Tests
