SYNTHESIS AND CHARACTERIZATION OF NEW (CHLOR0)AMINOSILANES: X-RAY CRYSTAL STRUCTURE OF [(2,6-Me2C6H3NH)2SiCl2]
摘要:
Starting from racemic alpha -methylbenzyl amine or alpha -methylbenzyl bromide, new (amino)trichlorosilanes (MePhC(H))(SiMe3)NSiCl3(1) and (MePhC(H))(2,6-Me2C6H3) NSiCl3 (2) have been synthesized in good yields. The products have been characterized by analytical and IR, mass, and NMR (H-1 and Si-29) spectroscopic techniques. The diamino-dichlorosilane (2,6-Me2C6H3NH)(2)SiCl2 (3) obtained as the side product during the synthesis of 2 has been characterized by a single crystal X-ray diffraction study.

A series of thirty‐three N,N′‐diaryl, dialkyl, and alkyl‐aryl ureas have been prepared in pyridine or toluene by reaction of silylamines with CO2. This protocol is shown to provide facile access to 13C‐labeled ureas, as well as chiral and macrocyclic ureas. These reactions proceed through initial generation of the corresponding silylcarbamates, which subsequently react with silylamine under thermal

silylamines 1, after conversion into their lithium or zinc salts, were readily oxidized by dry air under very mild conditions (−60° C to −20° C; 5–45 min.) into the corresponding aldehydes or ketones 2 in good yields. Our reaction conditions tolerate the presence of other oxidation sensitive functional groups like a phosphine, a thioether or a tertiary amine.

A range of alkylthionitroso and arylthionitroso compounds have been generated by thermal fragmentation of N-trimethylsilyl-N-chlorothioalkyl(aryl)amine precursors, and intercepted by reaction with dimethylbutadiene to afford Diels-Alder and ene adducts.
