Investigations of plasma production by a pulsed dye laser
microprobe were made. Comparisons between a Q- switched and a
pulsed dye laser system were made on the intensity of the continuum
produced by atmospheric breakdown. The dye laser system was
foundtominimize the production of the continuum which in turn
allowed...
Enantioselective epoxidation of crotyl alcohol, followed
by a cuprate mediated methylation, gave a 1:1 mixture of
(2S) -3- methyl -1,2- butanediol and (2R,3S)-2-methy1-1,3-
butanediol. The latter was separated as its 2,4,6-trimethylbenzenesulfonate
derivative and converted via the
iodide to the corresponding phosphonium salt. The separated
butanediol derivatives were independently transformed
to...
Thermal analysis was used to investigate the following seven
systems: H₂S-B₂F₄, SOF₂-B₂F₄, COC1₂-B₂F₄, SF₄-B₂F₄, Xe-BF₃, NF₃-BF₃, and NF₃-BC1₃. In two of the seven systems
compound formation was observed.
In the system, H₂S-B₂F₄ the compounds H₂S[superscript .]B₂F₄ and
2H₂S[superscript .]B₂F₄ are formed. The compound H₂S[superscript .]B₂F₄ has a melting
point of...
The production of C¹⁴O₂ metabolized from glucose labeled in
specific carbon atoms by homogenates of chick embryonic and adult
heart was compared by the radiorespirometric technique. Homogenates
of early (two to five days of incubation) embryo hearts were
found to utilize the phosphogluconate pathway of glucose catabolism
to a greater...
The retro-ene reaction of 2-vinylcyclohexanols occurs readily
in the vapor phase at 400-450° producing unsaturated carbonyl
compounds in good yields. The starting- materials were prepared in
general by the carbenoid addition reaction of ethyl diazoacetate,
appropriately substituted cyclohexene, and copper catalyst to
produce bicyclic esters which were reduced to the...
