## Abstract Phenyl [1โ^14^C] acetylene (0.012mCi/mmole) was synthesized in 12.5% yield from [1โ^14^C] acetic acid through [1โ^14^C] acetophenone, its semicarbazone, and 4โphenylโ[4โ^14^C] 1,2,3โselenadiazole obtained by selenium dioxide oxidation. Oxidative coupling gave 1,4โdiphenyl [1,4โ^14^C~2~]

## Abstract NโPhenylโ2โnaphthylamine has been synthesized (1) with ^14^C in positions 1, 4, 5 and 8, (2) with ^13^C in position 8 (small amounts of [1โ^13^C] naphthalene and 2โ[8โ^13^C]naphthylamine are formed as byโproducts), and (3) with the Nโphenyl nucleus uniformly labelled with ^14^C.
Specifically labelled phenylacetic acid and mandelic acid derivatives, metabolites of L-Dopa, have been synthesized via the intermediary labelled benzyl alcohols, which were prepared by reduction of the methyl esters of the appropriate benzoic acids. The benzyl alcohols have been converted to the co
