A method is described by which tritium-labeled alltrans retinoic acid of high specific activity (up to \(\sim 51\) \(\mathrm{Ci} / \mathrm{mmol}\) corresponding to \(85 \%\) of theoretical) is converted photolytically within a fraction of a second to a mixture of retinoic acid stereoisomers.

## Abstract The possibilities of tritium labelling of tofizopam (**1**) at high specific activity were investigated. Two methods, one by isotopic exchange, and one by catalysed halogenโ€tritium replacement were developed. The latter was found to be more rational, and **1** specifically labelled with

## Abstract Tritium labelled amitriptyline (__1__) of high specific activity was prepared. The tritium was incorporated by catalysed isotope exchange into the precursor dibenzosuberone, which had been previously converted into a cyclic ketal, in order to protect the oxoโ€group against reduction. It
