## Abstract The synthesis of ^14^C‐2,3 dimercapto sucinic acid (DMSA) is described. The starting material ^14^C‐2,3 succinic acid was brominated and then deshydrohalogenated to give acetylenedicarboxylic acid. This ^14^C‐acetylenic compound was transformed into ^14^C‐dithioacetylsuccinic acid. This
## Abstract Methyl iodide‐^14^C was condensed with 2‐(1‐lithio‐hept‐1‐yn‐6‐yl) 1,3‐dioxolanne **4** in presence of HMPT and benzene to give 2‐(oct‐2‐yn‐8‐yl‐1‐^14^C) 1,3‐dioxolanne **5**. Catalytic reduction of **5**, followed by acid hydrolysis led to pelargonic aldehyde 9‐^14^C 7. Condensation o
## Abstract Carbonation with ^14^CO~2~ of penylethynyl‐lithium has given rise to (carboxyl‐^14^C) phenylpropiolic acid with 75 % yield based on ^14^CO^2^. The latter condensed with 2‐naphthol by treating with polyphosphoric acid afforded (4‐^14^C) β‐naphthoflavone, purified by silicagel low pressur
