The purpose of this study was to determine if the preferences in
clothing fabrics and preferences in home furnishing fabrics are
similar or different in color, design size, and line. The
relationships of age, education, and training in color and design to
agreement of clothing fabrics and home furnishing fabrics...
The potassium salts of certain 1-vinylcycloalk-3-en-l-ols have
been found to undergo sigmatropic ring expansion rearrangements in
HMPA. Preliminary investigations of several benzo-substituted medium
ring systems were undertaken in order to determine which of these
was best suited for further study. A synthetic sequence leading to
the formation of 5-methy1-6-viny1-7,8,9,10-tetrahydro-6-benzocyclo-octenol,
which...
The (±) 8,9:13,14-diseco-norestradiol, a large ring hormone
analog, and its related derivatives, were prepared by a ring expansion
approach. The key step of this approach is the establishment of the
benzocyclododecenone system via the Caubere reaction. This step
not only provides a favorable ring size, it also sets the necessary...
The thermal and anionic rearrangements of substituted 1-vinyltrans-
cyclotridec-3-en-l-ol compounds have been studied to determine
what effects substituents would have on the sigmatropic shift when
placed on the two positions of the 1-vinyl group.
For the thermal rearrangements, the a-substituted vinyl-trans-cyclotridecenols
gave both the [3,3] and [1,3] shift products of...
The potassium salts of a series of 1-vinylcycloalk-3-en-l-ols were found to undergo ring expanding [1, 3]-sigmatropic shifts at 25° when dissolved in hexamethylphosphoramide (HMPA) or 1, 2-dimethoxyethane (DME) with 18-crown-6. The yields and reaction rates were compared with those of the corresponding Siloxy-Cope ring expansions. These anionic cases showed about...
Geophysical surveys in the Gulf of California provided
the data to construct contour maps of bathymetry, free-air
anomalies and total field magnetic anomalies for the area
north of 27° N. Major faults such as the Ballenas-
Salsipuedes, Tiburón, Guaymas, and the South Cerro Prieto
are clearly observable on these maps....
During the summer and fall of 1982, personnel from the Geophysics
Group in the School of Oceanography at Oregon State University conducted
an aeromagnetic survey in the northern Oregon Cascades to
assess geothermal potential and study the thermal evolution of the
Cascade volcanic arc.
Total field and low-pass filtered magnetic...
