(Chemical Equation Presented) A new family of unsaturated isonitriles has been prepared by the base-promoted ring-opening of oxazoles, offering an alternative to the conventional formamide dehydration route. These compounds undergo the full complement of multicomponent reactions for which isonitriles are known and offer the desirable trait of giving amide products that readily participate in acyl substitution reactions (hence, they are convertible). Moreover, they do not have the objectionable odors for which isonitriles are typically known, making them more accessible as reagents for organic synthesis. One focus of the work is isonitriles bearing perfluorinated alkyl groups that enable the ready separation of such reagents from nonfluorinated reaction products using the "light" fluorous method of fluorous solid-phase extraction.

Mono- and di-iodoperfluoroalkylethers were synthesized and their reactions, as well as those of iodofluoroalkanes, with 4-iodobenzil were investigated.The formation of C8F17C6H4CHO, C8F17C6H4CO2H, C8F17C6H4COCOC6H5, and C8F17OCF2CF2C6H4COCOC6H5 proceeded readily.No C8F17OCF2C6H4COCOC6H5 was produced from the reaction of C8F17OCF2I with 4-iodobenzil in the presence of copper bronze.Low yields of bridged bisbenzils were obtained from the coupling rections of ICF2CF2O(CF2)5OCF2CF2I and I(CF2CF2O)5CF2CF2I with 4-iodobenzil.Based on by-products formed, the operative mechanisms are postulated.
