General Description

Phosphorane, pentylidenetriphenyl- is a chemical compound with the molecular formula C26H25P. It is a type of phosphorane, which is a group of organophosphorus compounds that contain a directly bonded phosphorus atom. In the case of pentylidenetriphenyl- phosphorane, it consists of a phosphorus atom bonded to a pentylidene (CH3CH2CH2CH2C-) group and three phenyl (C6H5) groups. Phosphorane, pentylidenetriphenyl- may have applications in organic synthesis and as a reagent in chemical reactions due to its unique structural features and reactivity.

PROCESS FOR PREPARING A FORMYLALKENYL ALKOXYMETHYL ETHER COMPOUND AND PROCESSES FOR PREPARING CONJUGATED DIENE COMPOUNDS FROM THE SAME

The present invention provide for preparing a formylalkenyl alkoxymethyl ether compound of the following general formula (2): R3CH2OCH2O(CH2)aCH═CHCHO (2), wherein R3 represents a hydrogen atom, an n-alkyl group having 1 to 9 carbon atoms, or a phenyl group; and “a” represents an integer of 1 to 10, the process comprising: hydrolyzing a dialkoxyalkenyl alkoxymethyl ether compound of the following general formula (1): R3CH2OCH2O(CH2)aCH═CHCH(OR1)(OR2) (1), wherein R1 and R2 represent, independently of each other, a monovalent hydrocarbon group having 1 to 15 carbon atoms, or R1 and R2 may form together a divalent hydrocarbon group, R1-R2, having 2 to 10 carbon atoms; and R3 and “a” are as defined above, in the presence of an acid while removing an alcohol compound thus generated to form the formylalkenyl alkoxymethyl ether compound (2).

SYNTHESIS OF PHEROMONES, IV. CHEMISTRY OF THE WITTIG REACTION, I. EFFECTS OF REACTION CONDITIONS ON THE STEREOSELECTIVITY AND YIELD OF THE WITTIG REACTION

The reactions of nonstabilized triphenylphosphorus ylides with aldehydes have been studied in detail.The stereochemistry and yields of the alkene products are highly dependent upon base used for the generation of the ylide, the solvent and reaction temperature.The synthesis of sex pheromone components by Wittig reaction are also described.
