A clandestine approach to the synthesis of phenyl-2-propanone from phenylpropenes

A clandestine approach to the synthesis of phenyl-2-propanone from phenylpropenes. Dal Cason, Terry A.; Angelos, Sanford A.; Raney, Jack K. (North Cent. Lab. 103-79-7 are also occured in this study., Drug Enforc. Adm., Chicago, IL 60607, USA). J. Forensic Sci., 29(4), 1187-208 (English) 1984. CODEN: JFSCAS. ISSN: 0022-1198. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Phenyl-2-propanone (I) [103-79-7], a nonpsychoactive controlled substance and a primary precursor in a no. of syntheses for amphetamine and methamphetamine, was synthesized in good yield from chems. not normally assocd. with the clandestine synthesis of I. Thus, 2 published syntheses were modified for I manuf. by substitution of the chems. and through slight changes in procedure. In the allylbenzene [300-57-2] procedure, similar to that of J. Tsuji et al. 1981) for the prepn. of 1-decanone, the O balloon (an outside source of O) was replaced with 30% H2O2. PdCl2 catalyst was also reduced. I was obtained in 49% yield. trans-b-Methylstyrene, a by-product of this reaction was also converted to I in the 2nd procedure. There are some commonly used reagents like 103-79-7 in this article. This conversion was accomplished by dropping the styrene soln. in Me2CO into a stirred soln. of H2O2 in HCO3H. The yield was 93%. The spectral data are presented. ..

The identification of impurities in illicit methamphetamine exhibits by gas chromatography/mass spectrometry and nuclear magnetic resonance spectroscopy

The identification of impurities in illicit methamphetamine exhibits by gas chromatography/mass spectrometry and nuclear magnetic resonance spectroscopy. Kram, T. C.; Kruegel, A. V. (Spec. Test. Res. Lab., Drug Enforcement Adm., McLean, Va., USA). J. Forensic Sci., 22(1), 40-52 (English) 1977. CODEN: JFSCAS. ISSN: 0022-1198. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Impurities accumulated during the synthesis of methamphetamine [537-46-2], which is often manufd. illicitly, by the Leuckart reaction, e.g., Me benzyl ketone [103-79-7] and NH2Me [74-89-5], were identified by gas chromatog.-mass spectrometry and NMR spectroscopy. Impurity identification in finished products or in various intermediate stages of the Leuckart reaction is useful in the identification of seized clandestine methamphetamine. Only N-formylamphetamine [22148-75-0] can be assocd. specifically with the Leuckart synthesis of methamphetamine.
