| titleOfInvention | Gamma,delta-unsaturated alpha,alpha-dichlorocarbonyl compound and its preparation |
| abstract | NEW MATERIAL:The compound of formula I (R 1 is H, alkyl, alkenyl or aryl; R 2 WR 4 are H or lower alkyl; provided that R 1 WR 4 are not H at the same time). n EXAMPLE: 2,2,-Dichloro-1-phenyl-4-penten-1-one. n USE: A synthetic intermediate for the preparation of useful terpene compounds. n PROCESS: The ether of a 2,2,2-trichloroethyl compound and an allyl compound (formula II) is dehydrochlorinated by reacting in the presence of a base such as potassium tert-butoxide, in a solvent such as tetrahydrofuran, for several hours with or without heating. The objective compound of formula I can be prepared, in high efficiency, by the thermal rearrangement of the resulted ether of 2,2-dichlorovinyl compound and an allyl compound (formula III) at 100W150° for about 30min. n COPYRIGHT: (C)1982,JPO&Japio |
