Facile Synthesis of Carbon Monoxide Isotopically Labelled at Oxygen from Enriched Water without Isotopic Dilution
Ioset, Jacques,Roulet, Raymond
, p. 1659 - 1660 (1988)
O-Labelled carbon monoxide was prepared on the gram scale from enriched water and acetals of norborn-2-en-7-one (= bicyclohept-2-en-7-one) in almost quantitative yields and without isotopic dilution.
