Unusual Mass Spectrometric Fragmentation of N,N'-Diethyl-N,N'-diphenylurea
Hanus, V.,Horak, Z.,Tolman, V.
, p. 49 - 52 (1982)
The electron impact mass spectrum of N,N'-diethyl-N,N'-diphenylurea contains the ion m/z 164 which is of low abundance at normal energy of ionizing electrons but prominent at 15-20 eV.The mechanism of its formation has been revealed by means of labelled c
Reductive Fragmentation of Tetrazoles: Mechanistic Insights and Applications toward the Stereocontrolled Synthesis of 2,6-Polysubstituted Morpholines

A new methodology to synthesize 2,6-di-, and 2,2′,6-trisubstituted morpholines via the reduction of oxabicyclic tetrazoles under mild conditions is described. The reaction proved successful for a wide range of tetrazoles, including sterically encumbered ones harboring gem-substituents on tertiary carbon centers. The mechanism for the decades-old reduction of tetrazoles to secondary amines is elucidated.
Photochemical Desulphurization of Indoline-2-thiones
Nishio, Takehiko,Okuda, Norikazu,Kashima, Choji
, p. 141 - 143 (2007/10/02)
The photochemical reactions of indoline-2-thiones in the presence of amines have been examined.Irradiation of indoline-2-thiones 1 in the presence of triethylamine yielded the desulphurization products, indolines 2, along with N,N-diethylthioacetamide 3.T
