The methoxycarbonylation of aryl chlorides catalysed by

A catalyst system based on palladium-1,2-bis- (di- tert -butylphosphinomethyl)benzene (BDTBPMB) shows good activity for the methoxycarbonylation of strongly activated aryl chlorides, like 4-chloromethylbenzoate or 4-chlorocyanobenzene. Surprisingly, the use of less activated aryl chlorides, like 4-chloroacetophenone,

Cyclohexane conformation

The internal angles of a flat regular hexagon are 120, while the preferred angle between successive bonds in a carbon chain is about 109.5, the tetrahedral angle. Therefore, the cyclohexane ring tends to assume certain non-planar (warped) conformations, which have all angles closer to 109.5

2,6-DTBP contains a hydroxyl group that is chemically bonded to carbon on a benzene ring. The benzene ring is very stable by virtue of its aromaticity and di-tert-butyl groups are also stable and non-oxidizing. The molecule does not contain any halogens. Benzyl alcohols are considered to be very weak oxidizing agents.
