## Abstract Methyl cinnamate ‐3‐^14^C is reduced smoothly in excellent yield to cinnamyl alcohol ‐3‐^14^C by aluminum hydride. without attack of the double bond. After purification by column chromatography cinnamyl alcohol ‐3‐^14^C is obtained with a radioactive overall yield of 65% based on cinnam
## Abstract Methyl iodide ^14^C is reacted with lithium p‐methoxy phenylacetylenide to give with a 85% yield 1‐p‐methoxy‐phenyl‐1‐propyne‐3‐^14^C. Reduction of the latter with LiAlH~4~ leads to a mixture of trans anethole‐3‐^14^C (85%) and cis anethole (15%) with a 55% yield. After preparative gas
## Abstract (S)‐Fenvalerate (α‐cyano‐3‐phenoxybenzyl) (S)‐2‐(4‐chlorophenyl)‐3‐methylbutyrate, a novel insecticide, was labelled with carbon‐14 individually at the carbonyl (**1a**), the cyano (**1b**) and the alcoholic methyne (**1c**) carbons for use in metabolic studies. Isopropylation of 4‐chlo
