Formation of positive and negative ions in CH3NO2
Jiao,DeJoseph Jr.,Garscadden
, p. 9040 - 9044 (2003)
Absolute dissociative ionization cross-sections from threshold to 200 eV have been measured using Fourier transform mass spectrometry (FTMS). In the production of positive ions by electron impact ionization, 13 ions are detected, including the parent ion
IR Spectroscopy of the Gas Phase Formed after Interaction between CH3I and Ag-Containing Sorbents Based on Silica Gel

Abstract: IR spectra of the gas phase formed during the interaction between gaseous CH3I and SiO2-based granular sorbents containing various silver compounds are studied. It is established that the main gaseous products formed by the
Green synthesis of low-carbon chain nitroalkanes via a novel tandem reaction of ketones catalyzed by TS-1

A green and efficient one-pot method has been developed for the synthesis of low-carbon chain nitroalkanes via a novel TS-1 catalyzed tandem oxidation of ketones with H2O2 and NH3. The tandem reaction including ammoxidation, oximation and oxidation of oximes, afforded up to 88% yield and 98% chemo-selectivity requiring only 90 min, at 70 °C and atmospheric pressure. Moreover, this method was even amenable to 100-fold scale-up without loss of chemical efficiency with 87% yield, represents a significant advance towards industrial production of nitroalkanes. Furthermore, the plausible mechanism of TS-1 catalyzed tandem oxidation of ketones to prepare nitroalkanes was proposed.

Despite the high nucleophilicity of sulfur atoms, thiacalixarenes have been alkylated only on oxygen atoms thus far. Using strong alkylating agents (triflates, trialkyloxonium salts), the substitution of the sulfur bridges has been successfully accomplished. The corresponding sulfonium salts of thiacalix[4]arene are formed regio- and stereoselectively as a completely new type of substitution pattern in thiacalixarene chemistry. These compounds possess interesting conformational behavior and could be used as unusual alkylating agents with uncommon selectivity.
