Examination of a proposed reaction scheme to prepare bicyclo-(2.2.0)hexan-1-ol produced the first known condensation of an
enamine with its carbonyl precursor. Hydrolysis of the resulting
dienamine gave an unusual conjugated cyclobutenone in which the
double bond is exocyclic. Characterization and reactions of the
cyclobutenone were successfully carried out.
Cyclopropylcyclobutene was prepared via the intermediate
dicyclopropylcarbinyl carbene which was generated by the thermal
decomposition of the sodium salt of dicyclopropylketone p-toluenesulfonylhydrazone.
The successive thermal isomerization of cyclopropylcyclobutene
to 2-cyclopropyl-1, 3-butadiene and to vinylcyclopentene
was studied. Kinetic data were obtained for the cyclopropylcyclobutene
to 2-cyclopropyl-1, 3-butadiene isomerization in the gas...
The goal of this research was to mathematically simulate the ability of
bioaugmented microorganisms to aerobically cometabolize a mixture of chlorinated
aliphatic hydrocarbon (CAH) compounds during in-situ treatment. Parameter values
measured from laboratory experiments were applied to the transport model with
biotransformation processes included. In laboratory microcosm studies, a butane-grown,...
Butane-grown Pseudomonas butanovora oxidized butane by a soluble
butane monooxygenase through the terminal pathway yielding 1 -butanol as the
predominant product. Alcohol dehydrogenases (ADHs) involved in butane
oxidation in P. butanovora were purified and characterized at the biochemical,
genetic and physiological levels. Butane-grown P. butanovora expressed a type I
