Cyaclopentadienyl thallium has been prepared with one carbon position labeled at a concentration greater than 90 atom % carbon‐13. A new method for incorporating a carbon‐13 label into cyclopentadiene is reported which relies on the reaction of the di‐Grignard reagent of 1,4‐dibromobutane with isopropyl formate 13 C. The product of this reaction, cyclopentanol‐1‐ 13 C, is converted to cyclopentadienyl‐X‐ 13 C thallium.
