Photolysis and solvolysis of triarylbromoethanes 1 in the presence of alkoxide anions in alcohols resulted in significant formation of products derived from ipso substitution by alkoxide anions. Photolysis of 1-aryl-1-bromo-2,2-diphenylethenes 1Aa and 1Ab
Drastic Base Dependence of Products in Photolysis of 1-(p-Methoxyphenyl)-2,2-diphenylvinyl Bromide. ipso Substitution by Alkoxide Ions
Kitamura, Tsugio,Kabashima, Takashi,Kobayashi, Shinjiro,Taniguci, Hiroshi
, p. 1951 - 1954 (2007/10/02)
Addition of alkoxyde ions resulted in ipso substitution in the photolysis of an alcohol solution of 1-(p-methoxyphenyl)-2,2-diphenylvinyl bromide, whereas addition of triethylamine, pyridine, or NaHCO3 led to vinylic substitution.
ISOLATION AND ALCOHOLYSIS OF AN IPSO ADDUCT, VINYLIDENECYCLOHEXADIENE, FROM PHOTOLYSIS OF 1-(p-ETHOXYPHENYL)VINYL BROMIDE
Kitamura,Tsugio,Kabashima, Takashi,Kobayashi, Shinjiro,Taniguchi, Hiroshi
, p. 6141 - 6142 (2007/10/02)
An ipso adduct, vinylidenecyclohexadiene 2, was isolated from the title photolysis and showed exclusive transformation to the corresponding vinyl ethers by alcoholysis.
