Authors showed in previous article that in heating alpha and beta~-dimethylstgrol or
alpha, beta, betatrimethylstyrol with three equivalents of Bulfur:at 190-210 C
until complete cessation of precipitation of hydrogen sulfides, smoothiformatic~n
of betaphenylthiophene and beta-phenyl-betal-tbitolene results., Assuming that
this reaction has general significance, they tried to syntheS12e ~be remaining
two theoretically possible beta-phenylthiotolenes. Consequently,,jn realization of
the reaction of sulfur with alpha-methyl-beta-ethylstyrol and betameth~-l-alpha-
ethylstyrol,, obtained beta-phenylalpha-thiotolene and beta-phenyl;-alpha, thiolene
heretofore unknown. Submitted by Academician A. N. Terenin, 5 Jan' 1948.
