摘要:
The invention aims to provide a perylene derivative preparation process featuring satisfactory yields and improved preparation efficiency, a perylene derivative obtained by the process, and an organic EL device using the same. The object is achieved by a perylene derivative preparation process comprising subjecting to coupling reaction a 1,8-dihalogenated naphthalene derivative of the formula (1): wherein X is Cl, Br or I, R1 to R4, R11 and R12 each are hydrogen, alkyl, alkoxy, alkylthio, alkenyl, alkenyloxy, alkenylthio, aralkyl, aralkyloxy, aralkylthio, aryl, aryloxy, and arylthio radicals which may be substituted, amino radical, cyano radical, hydroxyl radical, —COOM1 radical (wherein M1 is hydrogen, alkyl, alkenyl, aralkyl or aryl), —COM2 radical (wherein M2 is hydrogen, alkyl, alkenyl, aralkyl, aryl or amino), or —OCOM3 radical (wherein M3 is alkyl, alkenyl, aralkyl or aryl), and at least two adjoining radicals selected from among R1 to R4, R11 and R12 may bond or fuse together to form a substituted or unsubstituted carbocyclic aliphatic ring, aromatic ring or fused aromatic ring with the carbon atoms on which they substitute, with the proviso that when the carbocyclic aliphatic ring, aromatic ring or fused aromatic ring has substituent radicals, the substituent radicals are the same as R1 to R4, R11 and R12, to thereby synthesize a perylene derivative of the formula (2): wherein R1′ to R4′, R11′ and R12′ are as defined for R1 to R4, R11 and R12 in formula (1), and R1 to R4, R11 and R12 and R1′ to R4′, R11′ and R12′ may be the same or different.
摘要:
Halohydrocarbons comprising at least 3 carbon atoms are obtained by reaction between a haloalkane and a haloolefin in the presence of an organonickel compound as catalyst, and optionally in the presence of a solvent. 1,1,1,3,3-Pentachlorobutane can thus be obtained in good yield under mild conditions.
摘要:
POLYCYCLIC BRIDGED RING COMPOUNDS ARE PRODUCED BY A TWO-STAGE PROCESS IN WHICH A SUBSTITUTED CYCLIC HYDROCARBON SUCH AS NORBORNENYL CHLORIDE IS CONDENSED WITH AN ACYCLIC CONJUGATED DIOLEFINE, E.G. BUTADIENE, ISOPRENE ETC. AND THE SUBSTITUENTS FROM THE CYCLIC HYDROCARBON SUBSEQUENTLY REMOVED TO PRODUCE A DOUBLE BOND. A PREFERRED SUBSTITUENT IS A HALOGEN ELIMINATED AS A HYDROGEN HALIDE. THE SUBSTITUTED CYCLIC HYDROCARBON MAY ITSELF BE PRODUCED FROM CYCLOPENTADIENE OR A NORBORNENE BY REACTION WITH AN ACYCLIC SUBSTITUTED OLEFINE SUCH AS VINYL CHLORIDE. THE PRODUCTS OF THE PROCESS HAVE UTILITY AS TERMONOMERS IN EPT RUBBERS, 1,4-ENDOMETHYLENE-6-METHYL-1,4,5,8,9,10HEXAHYDRONAPHTHALENE BEING PARTICULARLY USEFUL IN THIS RESPECT.
