A carbazole compound represented by the following formula: 

Carbazole compound and use thereof

An amine derivative represented by the following general formula (1) and exhibiting a temperature difference of 30&#xb0; C. or more as defined by the difference of [decomposition temperature (&#xb0; C.) minus sublimation temperature (&#xb0; C.)]: wherein Rand Rindependently represent a substituted or unsubstituted Caryl or Cheteroaryl group; and Rand Rindependently represent a hydrogen atom, a straight-chain, branched or cyclic Calkyl or Calkoxy group, or a substituted or unsubstituted Caryl or Cheteroaryl group, provided that Rand Rmay form together a cyclic hydrocarbon group. The amine derivative is useful as an organic electroluminescent material.

Amine derivative and organic electroluminescent element

A catalyst composition for a cross-coupling reaction comprising a nickel salt-amine complex of formula (1), and triphenylphosphine. where Rthru Rindependently represent alkyl, aryl, heteroaryl or alkenyl; n is an integer of 1-6; and X independently represents halo, hydroxyl, nitrate or acetate group. Using the catalyst composition, a cross-coupling reaction is carried out between a boron-containing compound of formula (2) and a compound of formula (3). where Rand Rare the same as R-Rdefined above; Y independently represents hydroxyl or alkoxy, Z is halo, methanesulfonate or trifluoromethanesulfonate.

Catalyst composition and process for producing cross-coupled compound using same

An acrylate compound of formula (4): is produced by allowing an acrylic acid compound of formula (1): to react with an unsaturated compound of formula (2) or (3): In formulae (1) through (4), Rand Rare H or F, Ris H, F, or an alkyl, alkenyl, fluoroalkyl or fluoroalkenyl group, Rand Rare H, halogen, or an alkyl, alkenyl, halogenated alkyl or halogenated alkenyl group; and X and Y are an unsubstituted or substituted hydrocarbon group, and dashed line - - - means that X and Y may be bonded together to form a cyclic structure.
