The present invention relates to a process for the synthesis of a carbon labeled organic compound containing a carbon labeled carboxyl group. The present invention also concerns the use of carbon labeled organic compounds containing a carbon labeled carboxyl group obtained by the process of the invention, in the manufacture of pharmaceuticals and agrochemicals, in particular pharmaceuticals and agrochemicals having a free carboxylic acid functionality. Another aspect of the invention relates to a process for manufacturing labeled pharmaceuticals and agrochemicals, in particular pharmaceuticals and agrochemicals having a free carboxylic acid functionality, comprising a step of synthesis of carbon labeled organic compounds containing a carbon labeled carboxyl obtained by the process of the invention A still another aspect of the invention further relates to a process for producing tracers and radiotracers, characterized in that it comprises a step of synthesis of carbon labeled organic compounds containing a carbon labeled carboxyl group obtained by the process of the invention.

A photocatalytic approach for carbonisotopeexchange is reported. Utilizing [13C]CO2 and [14C]CO2 as primary C1 sources, this protocol allows the insertion of the desired carbonisotope into phenyl acetic acids without the need for structural modifications or prefunctionalization in one single step. The exceptionally mild conditions required for this traceless transformation are in stark contrast
报道了用于碳同位素交换的光催化方法。利用[ 13 C] CO 2和[ 14 C] CO 2作为主要的C1来源,该方案可将所需的碳同位素插入苯基乙酸中,而无需在单个步骤中进行结构修饰或预功能化。这种无痕转化所需要的异常温和的条件与先前要求使用苛刻的热条件的方法形成了鲜明的对比。
