alpha -Nitrosoketal dimers and production of alpha -oximinoketals therefrom

摘要

This invention describes novel ketals of alpha -oximinoketones, methods for the preparation of these compounds and includes novel intermediates formed during the production thereof. The novel class of compounds disclosed herein includes both alpha -oximinoketals, as well as the cyclic ketals of alpha -oximinoketones. This invention also discloses a novel class of alpha -nitrosoketal dimers produced during the synthesis of the corresponding alpha -oximinoketals, and it also discloses novel methods in the production thereof.
