Tert.-Butyl-diallyl

When diallyl diazomalonate or allyl aryldiazoacetates are used as substrates in the rhodium-catalyzed reaction with di(tert-butyl)thioketene, 4-allyl-l,3-oxathiolan-5-one derivatives of type 158 are formed (82). After the initial 1,5-dipolar electro-cyclization, 157a undergoes a subsequent Claisen rearrangement to give the thermodynamically more stable compound 158 (Scheme 5.47).

Blending resin is obtained from emulsion pol5mierization of vinyl chloride in the presence of gelatin, polyvinyl pyrrolidone, diallyl phthalate, sodium dodecyl-benzene sulfonate, tert-butyl pivalate, and dissodium hydrogen phosphate. The surface of this product has a very limited light reflection and it does not stick to the same product. 

Li and co-workers developed a CDC allylic alleviation between allylic sp C-H and methylenic sp C-H bonds. By using a combination of CuBr and C0CI2 as the catalyst and a stoichiometric amount of TBHP (tert-butyl hydroperoxide) as the oxidant, various 1,3-dicarbonyl compounds reacted smoothly with cyclohexene and gave the desired products in moderate yields (Scheme 5.3). Sensitive substituents such as chloro and bromo were tolerated under the optimized reaction conditions. Other cyclic alkenes including diallylic systems were also transformed into the desired products when...
