of the inherently large barrier to rotation and the resultant thermal decomposition pathway is discussed. Both phenomena are shown to be solvent independent; hinderedrotation is substrate independent. The decomposition of 1a is ca. 7 kcal/mol higher than the barrier to rotationabout the S−S bond. The combined evidence suggests acyclic unsymmetric homolytic cleavage of the dialkoxy disulfide.

The chemistry of the generation and trapping of diatomicsulfur (S2) and sulfur monoxide (SO) are reviewed with special emphasis on recent work, including initial efforts to detect and trap diatomic selenium (Se2).

fragmentation to liberate trappable S2, and can yield an alkoxy radical under photolytic conditions. We have examined a family of benzylic dialkoxy disulfides (X–Ph–CH2–O–S–S–O–CH2–Ph–X) under photolytic conditions and observed a correlation of decomposition based upon the substituent. We have been able to show that the decomposition is autocatalyzed and has a parabolic correlation with Swain and Lupton’s
Disclosed is a method of inhibiting the growth of microorganisms in, at, or on a locus subject to microbial attack, comprising introducing to said locus an antimicrobially effective amount of at least one alkoxy disulfide of formula:R1-CHR3-O-S-S-O-CHR4-R2 wherein:
R1, R2are independently selected from 5- or 6-membered aromatic rings, optionally substituted with up to 3 e· donating substituents of which 2 can optionally be combined to form another ring; and
R3, R4are independently selected from H, CH3, or CH2CH3.
