ChemInform Abstract: THERMAL SPLITTING OF N‐TRIMETHYLSILYL‐N‐(2,2,2‐TRICHLORO‐1‐ALKOXY(AROXY))ETHYLUREAS AND ‐URETHANES

Abstract

Aus den Isocyanaten (II) und Trimethylsilyl‐diethyl‐ amin (I) entstehen die Addukte (III), die zu Harnstoffen (IV) hydrolysieren und bei der thermischen Spaltung im Vakuum zu Chloraliminen (V) und Alkoxysilanen (VI) zerlegt werden.

N-Functionally substituted imines of polychlorinated (brominated) aldehydes and ketones

“…68 The compound 11a was obtained in the reaction of diethyl(trimethylsilyl)amine with 1-alkoxytrichloroethyl isocyanates; the first stage of the reaction yields silylated ureas, which decompose on heating to give the imine 11d and the corresponding alkoxysilanes. 69 This method was used to synthesise a large number of acyl-, alkoxy(aryloxy)(thio)carbonyl-and N H -substituted carbamoylimines of chloral and trichloromethyl aryl ketones.…”
