Process for the preparation of a fluorine containing organic molecule, which process comprises the steps of a) preparation of a compound of the formula (I) wherein R1, R2 and R3 are independently hydrogen, fluor or an optionally fluorinated hydrocarbon group by feeding a compound of the formula (II) wherein R1, R2 and R3 are defined as above, and hydrogen bromide into a reaction zone, thereby producing a reaction mixture containing the compound of formula (II) and hydrogen bromide and irradiating said reaction mixture with UV light, and b) substituting the bromo atom in the compound of the formula (I) with another functional group to obtain the fluorine containing organic molecule. The invention allows also in particular for obtaining substantially anhydrous fluoroalcohols. The preparation of alcohols analogous to the bromides of formula (I) from the corresponding esters is also disclosed.

A Pd-catalyzedregioselectivehydroesterification of alkyl terminal olefins with aryl formates is described. A wide variety of linear carboxylic esters bearing various functional groups can be obtained in good yields with high regioselectivities under mild reaction conditions by using 1,2-DTBPMB or (p-F-Ph)3P as ligand. The reaction process is operationally simple and requires no handling of toxic
描述了烷基末端烯烃与甲酸芳基酯的 Pd 催化区域选择性加氢酯化反应。以1,2-DTBPMB或( p -F-Ph) 3 P为配体,在温和的反应条件下,可以高产率、高区域选择性地获得多种带有各种官能团的直链羧酸酯。该反应过程操作简单,不需要处理有毒的CO或强酸。所得芳基酯可以容易地转化为其他羧酸衍生物。
