Halogenated, unsaturated alcohols are dehydrated by contacting the alcohol and a carrier gas with a silica alumina catalyst to form dienes of the formula: ##STR1## wherein each X is independently hydrogen, fluorine chlorine, or bromine with the proviso that no more than one of them is hydrogen, and each R is independently hydrogen, alkyl, aralkyl, alkaryl, or aryl.

Some new cyanoacetates were synthesized and characterized. They are precursors for alpha-cyanoacrylates used as rapidly polymerized, cold-hardening adhesives.

Aryl trichlorovinyl ketones undergo regioselective reduction to the corresponding carbinols with sodium borohydride in alcoholic solvents and are transformed to the (Z)-alpha-chlorocinnamate ester derivatives via an acid-catalyzed allylic rearrangement. Michael addition of ammonia to these ester derivatives affords cis- and/or trans-aziridine amides. The facile rearrangement allows the synthesis of d,l-phenylalanine derived from perchloroethylene and toluene.
