Abstract: The invention relates to a process for preparing trialkylgallium compounds of the general formula R3Ga. The process is based on the reaction of gallium trichloride (GaCh), optionally in a mixture with partially alkylated products, with an alkylaluminium compound of the type RaAICIb (where R?C1-C5-alkyl, a=1, 2 or 3, b=0, 1 or 2 and a+b=3) in the presence of at least two alkali metal halides (e.g. NaCI and KCI) as auxiliary base. Preference is given to using alkylaluminium sesquichloride (R3AI2CI3) or trialkylaluminium (R3AI). The reaction mixture is heated to a temperature in the range from 120° C. to 250° C. and the trialkylgallium compound formed is separated off via a separator which is operated at a temperature which is more than 30° C. below the boiling point of the most volatile partially alkylated product. Complete alkylation is achieved here and partially alkylated products are recirculated to the reaction mixture. In a further step, the reaction mixture can be heated to a maximum of 350° C.

Abstract: A method for preparing a radiotracer precursor SnADAM is revealed. The method overcomes shortcomings of conventional synthesis methods including lower yield rate and time-consuming. Moreover, Pd/C catalyst and hydrogen gas are used to catalyze reduction reaction for avoiding the generation of a large amount of intermediate products with similar structures. Thus there is no need to perform isolation and purification processes. The yield rate of the intermediate products is also increased so that its impact on the low yield rate of the final product SnADAM is minimized. A part of the reaction is significantly accelerated by using tris(dibenzylideneacetone)-dipalladium(0) (Pd2(dba)3) as a catalyst. Thus the production time of SnADAM is shortened.
