non 1:1 ratio of alcohol to aldehyde reaffirms Harpp’s-postulated cage mechanism. We have shown that the ratio is dependant upon the substituent present which can enhance the pi-stacking ability with the solvent, and thus favor diffusion out of the solvation cage yielding the non 1:1 ratio observed.

Dialkoxy disulfides have found applications in the realm of organic synthesis as an S2 or alkoxy donor, under thermal and photolytic decompositions conditions, respectively. Spectrally, dibenzyloxy disulfides possess an ABq in the (1)H NMR, which can shift by over 1.1ppm depending on the substituents present on the aromatic ring, as well as the solvent employed. The effect of the said substituents and solvent

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).
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.

sulfoxylates (7b, 4-NO(2); 7c, 4-Cl; 7d, 4-CH(3)O, 7e: 4-CH(3)) are reported. The unexpected stability of 7b has permitted the first X-ray determination at room temperature of a sulfoxylate. The thermalisomerization of sulfoxylates 7b-c to sulfinates 8b-c was studied in different solvents (toluene-d(8), CDCl(3), and CD(3)CN) and interpreted as a concerted unimolecular process following first-order kinetics
