Abstract

1301936 1-Alkenyl isocyanates; t-alkyl halides BADISCHE ANILIN- & SODA-FABRIK AG 1 May 1970 [2 May 1969] 21027/70 Heading C2C 1-Alkenyl isocyanates of the formula wherein the R<SP>1</SP> groups are independently hydrogen atoms or alkyl, cycloalkyl, aralkyl or aryl radicals or two of them complete carbocyclic rings, are obtained by subjecting to thermal cleavage N - (1 - alkenyl) - N - talkylcarbamyl halides of the formula wherein R<SP>2</SP> is an optionally-substituted t.alkyl group and X is a halogen atom. t-Alkyl halides may be obtained as byproducts of the above process.
