Direct structure determination of the self-condensation product of 1-phenylpentane-2,4-dione using T1 and NOE measurements from carbon-13 NMR spectroscopy: Direct structure determination of the self-condensation product of 1-phenylpentane-2,4-dione using T1 and NOE measurements from carbon-13 NMR spectroscopy. Leon, V.; Espidel, J.; Bolivar, R. A. (Cent. Fis. Quim., Inst. Venez. Invest. Cient., Caracas, Venez.). Org. Magn. 64648-09-5 and 3318-61-4 are cas registry numbers of chemicals which are used as reagents here. Reson., 21(12), 766-9 (English) 1983. CODEN: ORMRBD. ISSN: 0030-4921. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Values of T1 and NOE, measured with broad-band proton irradn. were for the structure detn. of the self-condensation product of 1-phenylpentane-2,4-dione, and it was concluded that the previous assignment of the 13C NMR spectrum was erroneous. An independent proof of the new assignment is given using the selective collapse of the fine structure under low-power irradn. of the Me protons. .
