“…In contrast to most known radical and ionic additions, sulfenyl chloride additions do not give 1,4 adducts. Brintzinger and Ellwanger (1954) reported the addition to cyclopentadiene assuming a 1,4 mechanism which we have shown to be incorrect on the basis of detailed instrumental analysis.…”

“…The structure of the sulfides 3а,b was also confirmed by alternative synthesis which consisted in the interaction of 2-R-3mercapto-1,4-naphthoquinones [38,55] with 2-chloro-1phenylethanole with subsequent treatment of the product by thionyl chloride. Addition of cyclopentadiene to 2-amino-3-sulfenyl-1,4-naphthoquinone 2 took place in positions 1 and 4 of cyclopentadiene fragment [56].…”
Conditions of sulfenyl chlorides of substituted 1,4-naphthoquinone reactions with unsaturated compounds with the formation of new sulfides, thiones and 2-thiabicyclo[2.2.1]heptene and thiopyrane substances have been investigated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
