“…Aza- ortho -xylylenes generated from 3-alkylbenzosultams do not enter [4+2] cycloaddition but undergo a [1,5] sigmatropic hydrogen shift leading to 2-vinylaniline derivatives. − A domino reaction consisting of a series of pericyclic processes including cheletropic extrusion of SO 2 , [1,5] sigmatropic hydrogen shift, and [4+2] cycloaddition takes place in thermally initiated transformation of 1-allyl-4-nitrobenzosultams. , Thus, 1-methyl-3-allyl derivative of benzosultam undergoes thermolysis to 1-arylbuta-1,3-diene, which can be trapped by N -phenylmaleimide to form phenanthrolinone (Scheme 130) …”

“…6 (C) As an efficient chlorination reagent hexachloroethane can also substitute TMS and TIPS group to synthesize a series of chlorinous compounds. Shindoh et al prepared 6-trifluoromethyl-4-chloromethyl-2-phenylquinoline using C 2 Cl 6 and CsF in acetonitrile from 6-trifluoromethyl-4-(triisopropylsilyl)methyl-2-phenylquinoline. 7 Capello and co-workers also described an efficient chemoselective synthesis of (TMS) 3 SiPClTMS and (TMS) 3 …”

“…In these instances [1,5]-sigmatropic hydrogen shift occurs leading to 2-alkenylanilines. 4 In our previous papers we employed this process to the synthesis of 2-arylindenes, 5 1-and 2arylbutadienes, 4,6 cycloalkenylpyridines, 7 and a-(alkylthio)-ortho-aminostyrenes, 8 aryldihydrothiophenes, 8 and aryldithiopyrans. 8 In this paper we present results of our studies on aza-ortho-xylylene-mediated synthesis of arylcyclopentadienes.…”
