Abstract

1‐Pentene‐4‐^14^C and 1‐pentene‐5‐^14^C were obtained in one single step from iodoethane‐1‐^14^C and iodoethane‐2‐^14^C, respectively, by reaction with allylmagnesium chloride in tetrahydrofurfuroxytetrahydropyran (TFTP) as solvent. The synthesis was carried out on a twenty mmoles scale in a completely closed apparatus. The pentenes were formed in 80 % yield. After final purification by means of gas‐liquid chromatography the radio‐chemical purity was 99.7 %.

## Abstract A simple one‐step syntheses of 2‐([^14^C]‐methyl) furan and 4‐oxo‐[5‐^14^C]‐2‐pentenal have been described. Carbon‐14 labeled 2‐methylfuran was synthesized by treatment of 2‐furyl lithium with ^14^C‐methyl iodide, and ^14^C‐acetylacrolein was obtained by peracid oxidation of labeled 2‐m
