Low pressure vinylation of aryl and vinyl halides via Heck-Mizoroki reactions using ethylene
Smith, Craig R.,RajanBabu
scheme or table, p. 1102 - 1110 (2010/03/25)
Aryl bromides and iodides in the presence of catalytic amounts of a palladacycle derived from acetophenone oxime and 2 equiv of potassium acetate react with ethylene under ambient pressure (15-30 psi) to give the corresponding vinylarenes. The reactions work with both electron-deficient and electron-rich aryl compounds and tolerate wide variety of common functional groups. Vinyl bromides lead to 1,3-dienes in moderate yields.

, (2008/06/13)
A process for producing a halobiphenyl derivative represented by the following formula (I) comprises dehydrogenating a cyclohexylhalobenzene represented by the following formula (II) under such conditions that substantially no dehalogenation occurs. STR1 wherein X represents a halogen atom, and each of R1 and R2 independently represents a group represented by the formula STR2 wherein A represents carboxyl or an alkoxycarbonyl group and R represents a hydrogen atom or a lower alkyl group; an alkylcarbonyl; alkenyl; alkynyl; alkyl; aryl; arylcarbonyl; hydroxyalkyl; cyanoalkyl or cyanoalkenyl group.
