Evidence for heterolytic cleavage of C-S bonds in the photolysis of 1,3,5-trithianes

The homolytic/heterolytic nature of photolytic C-S bond cleavage was studied in 1,3,5-trithianes. The mechanism of photolysis was refined from previous studies. First, evidence was presented for the existence of a precursor of the biradical-like transient (I) which itself was identified in previous studies. Second, the nature of I was further clarified through methanol-scavenging experiments where the results could be interpreted as lending credibility to the notion that I has significant bipolar character. Kinetic and spectral analyses of transient absorptions, following laser excitation of the trithianes, showed that I was reacting with methanol. Complementary steady-state photolytic quantum yields supported this finding, and additional, but unidentified, stable products from irradiations in methanol were seen in the HPLC. The formation of these products was interpreted as likely arising from a nucleophilic attack of methanol at the carbocationic end of the bipolar structure of I.

Silyl thioketones are easily converted into the corresponding trimers (1,3,5-trithianes) under acidic conditions.Both the α-(cis,trans)-and the β-(cis,cis)-isomers were isolated.The β-diastereoisomers predominate over the α-form.The major isomer from the

REACTIONS OF 2,4,6-TRIARYL-DIHYDRO-1,3,5-DITHIAZINES WITH ELECTROPHILIC REAGENTS

2,4,6-Triaryl-dihydro-1,3,5-dithiazines reacted with electrophilic reagents such as p-TsOH*H2O, CF3COOH, HCl, and BF3*OEt2 under reflux in CH3CN to afford α-2,4,6-triaryl-1,3,5-trithianes and β-isomers (3a-d) in good yields.Reaction with I2 gave selectively 3a-d in high yields, while with ICl or IBr gave 3a-d and p-substituted benzylideneamine*HY.
