The rearrangement of arylselenenamides: The rearrangement of arylselenenamides. Southwell-Keely, P. T.; Johnstone, I. L. 62-53-3 and 34837-55-3 are cas registry numbers. These chemicals are also mentioned in this article.; Cole, E. R. (Sch. Wool Pastoral Sci., Univ. New South Wales, Kensington, Aust.). Phosphorus Sulfur, 1(2-3), 261-2 (English) 1976. CODEN: PREEDF. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Attempts to synthesize N-phenylbenzeneselenenamide always produced the isomeric p-aminodiphenyl selenide, probably as a result of an acid-catalyzed rearrangement. The case with which this rearrangement occurs is contrasted with the forcing conditions required for the analogous rearrangement of sulfenamides. .

Investigation into direct use of protected 3,4-dehydropyroglutamates in synthesis: Investigation into direct use of protected 3,4-dehydropyroglutamates in synthesis. Moody, Claire M.; Young, Douglas W.Several reagents such as 34837-55-3 is used here. (Department of Chemistry, University of Sussex, Brighton BN1 9QJ, UK). Journal of Chemical Research, (7), 478-480 (English) 2005 Science Reviews. CODEN: JCROA4. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Synthesis of the 3,4-dehydropyroglutamate I has shown it to be unstable, forming the dimer II on chromatog. and being too readily racemized to be considered as a useful chiral synthon. .
