| Abstract: | Unambiguous 13C-NMR assignments for the olefinic carbons of 1,3-cyclohexadiene (in CDCl3: δC(1) = 126.02 ppm and δC(2) = 124.30 ppm downfield from TMS) have been made by comparison with regioselectively synthesized 2-deuterio-1,3-cyclohexadiene (in CDCl3: δC(1) = 125.88, δC(3) = 124.22 and δC(4) = 126.02 downfield from TMS). 1H-NMR chemical shifts and splittings are shown for both compounds. |
