Ka. Ginige et al., SULFONYL ESTERS .7. THE 2ND AND 3RD SEQUENCES IN THE TRITHIOORTHOFORMATE REACTION, Canadian journal of chemistry, 74(9), 1996, pp. 1638-1648
A previous report has established the intermediacy of a sulfide-sulfon
ate ester in the one-pot conversion of an aryl mercaptan and a sulfona
te ester into the corresponding trithioorthoformate. This report descr
ibes evidence for the sequential intermediacy of a bissulfide-sulfonat
e ester and a dithiosulfene in the conversion of the sulfide-sulfonate
ester into the trithioorthoformate. A new sulfonate ester is shown to
give the highest yield of trithioorthoformate.
