Photolysis methanethiol

We now turn to methanethiol, the near-UV photochemistry of which has received considerable attention of late. As with methanol, early photochemical studies had succeeded in showing that the primary photolysis channel at long wavelengths involved S—H bond fission (dissociation pathway shown in Eq. 8), even though C—S bond fission (channel shown in Eq. 9) is energetically more favorable.

CF2 CFa CF2 CF SAg (not isolated) -- (with EtI at 75 °C) CF2 CF2 CF2 CF SEt (21%). Raman and photoelectron spectral data are available for some CFs S-compounds, and so are e.s.r. parameters for the radical CFs S CHs-CBu a [generated via photolysis of a solution of the appropriate olefin in (CFs-S)2]. Unsuccessful attempts have been made to generate a radical anion via electrochemical or chemical (NaK alloy) reduction of 3,4-bis(tri luoromethyl)-l,2-dithieten. i Reactions between trifluoromethanesulphenyl chloride and JV-chloro-amines are portrayed in Scheme 26 (p. 216) and some involving hexafluorothioacetone dimer in Scheme 27 (p. 217) many unsuccessful attempts are claimed to have been made to isolate bis(trifluoromethyl)methanethiol from the products of the reactions of the dimer with amines, the conversion into hexafluoroisopropylidenimines being...
