Solvolysis of secondary alkyl p-toluenesulfonates with: Solvolysis of secondary alkyl p-toluenesulfonates with .beta.-dimethyl and .beta.-nitro, sulfinyl, sulfonyl, or phosphonoyl substituents: fragmentation vs. rearrangement. Brownbridge, Peter; Hodgson, Philip K. G.; Shepherd, Robin; Warren, Stuart (Univ. Chem. Lab., Univ. Cambridge, Cambridge, Engl.). J. Chem. Soc., Perkin Trans.In this article, certain chemicals are used. Some of their cas registry numbers are 62336-80-5 and 5042-53-5 1, (19), 2024-34 (English) 1976. CODEN: JCPRB4. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The effect is reported of electroneg. substituents based on CO, PO, SO, and NO at adjacent C atoms on the solvolysis of alkyl toluenesulfonates. Solvolysis of nitro- or phosphonoyl-contg. toluenesulfonates resulted in decompn. of the mol. and formation of electrophilic fragments, e.g., O2NCMe2CHMeO3SC6H4Me-p gave Me2C:CHMe, NO2+ and p-MeC6H4SO3-. Phenylsulfinyl, -sulfonyl, and, in one case, carbonyl substituents migrated to the secondary C atom on solvolysis. E.g., PhSOCMe2CHMeO3SC6H4Me-p gave PhSOCHMeCMe:CH2. The results are compared with those for other electroneg. groups where 1,4-participation may occur. Kinetic data for the solvolyses are reported. .

New synthesis of butenolides and g-phenylthio acrylic esters: New synthesis of butenolides and g-phenylthio acrylic esters. Brownbridge, Peter; Warren, Stuart (Chem. Lab., Univ. Cambridge, Cambridge, Engl.). J.Chemical with cas number 5042-53-5 also plays role. Chem. Soc., Chem. Commun., (13), 465-6 (English) 1977. CODEN: JCCCAT. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Alkylation of the enolate anions of a-phenylthio ketones with ICH2CO2- followed by redn. 5042-53-5 which is the cas registry number is also used here. gave b-(phenylthio)butanolides which on oxidn. and acid-catalyzed rearrangement gave butenolides and g-phenylthioacrylic esters, resp. E.g., PhSCH2COMe with NaH and ICH2CO2- gave 80% PhSCH(CH2CO2H)COMe which on NaBH4 redn. gave 98% butanolide I. I with NaIO4 gave the corresponding sulfoxide which underwent regioselective thermal decompn. to the butenolide II. I underwent rearrangement in C6H6 in the presence of 4-MeC6H4SO3H and an alc., e.g. EtOH, to give PhSCHMeCH:CHCO2Me. ..
