Some chemical and photochemical observations of 1,2-dithiolane and its
derivatives are reported with particular reference to the possible mode of
function of the naturally occurring system, 6-thioctic acid. Experimental
evidence is presented to demonstrate that the strain energy in this 5-membered
ring is not less than 6.5 Kals. and probably larger. Reagents which both
oxidize and reduce this ring are described together with the conditions required
for its reformation from the corresponding dithiol. Evidence is adduced to in-
dicate that the primary product of photolysis of this ring in acetic media is
very likely a thiol and sulfenic acid or derivative thereof.
Here’s what’s next.
