The absorption, translocation and metabolism of a new
herbicide, n-propyl-C¹⁴ N, N-di-n-propyl-thiolcarbamate (PDPC), were
studied in both peanut and soybean plants. These studies were
carried out on plants of different ages and treated at two rates of
application. The residue content of the plants was also determined
from germination to...
Although 4- and 5-diacetamidopyrimidines have been reported
in the literature within the past eleven years, it was not until 1965
that a 2-diacetamidopyrimidine was reported. The current investigation
was undertaken to determine whether other 2-diacetamidopyrimi-dines could be synthesized and what the effect of various nuclear substituents would be on the...
Part I describes the synthesis of bis(fac-S)((tris)2-aminoethanethiolatoiron( III))iron(III) chloride. The compound was first discovered during an attempt to prepare a ternary complex of iron, thiolate and pi-acid ligand. The compound is a reasonably air-stable iron(III)-thiolate that contains a linear tri-iron cluster with each iron bridged to the adjacent iron by...
Diffusion of short chain n-alkanes was found to be faster in the
polydimethylsilicone elastomer SE-30 than in the polydimethylsilicone
oil SF-96-2000. The opposite was true for the longer chain n-alkanes
suggesting that choice of stationary phase for gas chromatography
would depend on the chain length of sample components. The dependence...
A preparative method for a new compound n-octadecylcycloazadi-boron (CAB), in high yield has been developed. CAB was isolated as
an intermediate in the octadecylamine-catalyzed hydrolysis of pentaborane.
The most probable structure of CAB can be regarded as a
derivative of the three membered ring cycloazadiboron with a
n-octadecyl group substituted...
The reaction of certain purin-8-ols with phosphorus
oxychloride and N,N-diethylaniline are described.
9-Amino-6-chloropurin-8-ol monohydrate reacted with
phosphorus oxychloride and N, N-diethylaniline to yield
the phosphorus oxychloride adduct. Other purin-8-ols
were prepared and the production of analogs similar to
the previously mentioned adduct was attempted.
6-Chloropurin-8-ol and 6, 9-diaminopurin-8-ol hydrochloride
monohydrate...
Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic compounds gaining notoriety as contaminants of emerging concern. With the frequent detection of PFAS in the environment, drinking water, and consumer products, awareness and concern from the public regarding PFAS is increasing. The two most notorious PFAS are perfluorooctanoate (PFOA)...
