Water and methanol adsorption isotherms at 25° and 37° C.
were determined on a series of organo-bentonite clays. The clays
differed in the length of the carbon chain attached to the amine adsorbed
in the cation exchange position. The amines used had carbon
chains of 4, 6, 8, 10, 12,...
The preparation of 4-(3-hydroxypropyl) cyclohexanone and
of 4-(3-hydroxypropyl) cyclohexene and a number of their derivatives
as potential precursors of asymmetrically substituted bicyclo [3, 3, 1]
nonanes is described.
The ketone, 4-(3-hydroxypropyl) cyclohexanone, was prepared
from p-allylanisole by three different routes. Common to each
route was an initial hydroboration-oxidation followed by...
An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The
Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride
with aluminum chloride was shown to give one bicyclic chlorine
containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...
1-(2-pyridyl)-3-methyl-3-butene-2-ol was prepared by allowing 2-picolyllithium to react with methacrolein.
In the reaction of picolyllithium with crotonaldehyde, two products 1-(2-pyridyl)-4-methyl-3-butene-2-ol and 1-(2-pyridyl)-4-methyl-2-butene-4-ol were formed.
1-(2-pyridyl)-3-methyl-3-butene-2-ol was subjected to the low
pressure hydrogenation, using methanol as solvent and PtO₂ as catalyst. A red yellow liquid 1-(2-pyridyl)-3-methyl-2-butanol was
obtained. Derivatives of the...
