| description | The invention is directed to a new process for the preparation of carbinols of the general formula I I by reaction chloral and olefins of the general formula II and by optional acylation of the product comprising dissolving a catalyst of the general formula III Fen(NH4)xYmxAp III in chloral, then adding the olefin of the general formula II in order to produce a complex of the general formula IV IV from which a complex of the general formula V V is formed, and from the reaction mixture a compound of the general formula I is obtained whereafter (a) the residual complex of the general formula V dissolved in the product is decomposed with an acidic solution and if desired the obtained product is distilled or (b) the product in the reaction mixture is acylated. The compounds prepared according to the invention can be utilized as intermediates when preparing e.g., permethrin and other pyrethroid insecticides. |
