The Front Cover shows an artist's impression of the self-assembly spin-crossover complexes modified with alkyl tails. These iron-containing molecules can switch between a non-magnetic, low-spin state, and paramagnetic, high-spin state. Randomly oriented in bulk, they formed highly ordered monolayers by when were deposited on pyrolytic graphene surface. Such assemblies magnetically switchable re...

Microsomal enzymes from Ehrlich ascites tumors synthesized 0-alkyl glyceryl ethers from hexadecanol and dihydroxyacetone phosphate in the presence of ATP, CoA, and Mg++. Glyceryl ether synthesis occurred via the formation of 0-alkyldihydroxyacetone phosphate and O-alkyldihydroxyacetone. Although NADPH inhibited the initial reaction of dihydroxyacetone phosphate with fatty alcohol, it was requir...

Information on the biosynthesis of the D-arabinans of the cell wall of Mycobacterium tuberculosis is rapidly emerging, with the promise of new targets for drug development against tuberculosis. Accordingly, arabinosyl transferase assays were developed utilizing synthesized [1-14C]-beta-D-arabinofuranosyl-1-monophosphoryldecaprenol as donor and a variety of O- and S-alkyl arabinosides as accepto...

While suberin is an insoluble heteropolymer, a number of soluble lipids can be extracted by rapid chloroform dipping of roots. These extracts include esters of saturated long-chain primary alcohols and hydroxycinnamic acids. Such fatty alcohols and hydroxycinnamic acids are also present in suberin. We demonstrate that alkyl coumarates and caffeates, which are the major components of Arabidopsis...

sec-Alkyl radicals are key reactive intermediates in the hydrocarbon combustion and atmospheric decomposition mechanisms that are formed by the abstraction of hydrogen from an alkane, or as a second generation product of n-alkyl H-migrations, C-C bond scissions in branched alkyl radicals, or the bimolecular reaction between olefins and n-alkyl radicals. Since alkanes and branched alkanes, which...

Alkyl nitrites have been problematic worldwide due to their recreational use. Although there is a lack of scientific information on their action on the central nervous system (CNS), many anecdotal reports and case studies have inferred the CNS actions of alkyl nitrites. The objective of this study was to investigate the effects of alkyl nitrites on the CNS, especially focusing on the dopaminerg...

The 02, CO, and alkyl isocyanide-binding properties of a variety of vertebrate and invertebrate heme proteins have been compared in detail to those of protoheme mOn0-3-( 1-imidazoy1)-propylamide monomethyl ester in aqueous suspensions of soap micelles. The proteins examined include: cytochrome P-450,,, from Pseudomonasputida, beef heart cytochrome c oxidase, yeast cytochrome c peroxidase, a and...

Sir: We recently reported 1 that cobaloximes and cobalamins reacted with vinyl ethers, in the presence of alcohols, to give aceta Is containing cobalt-carbon cr-bonds. On the basis of these, and earlier 2 experiments, we suggested that the reactions proceeded via the intermediary of a Co(lII)-olefin 7r-complex. Schrauzer, et al.,3 then reported that they were unable to confirm our results and c...

Ethane 1,2-diamineborane (EDAB) is an alkyl-containing amine-borane adduct with improved hydrogen desorption properties as compared to ammonia borane. In this work, it is reported the high temperature thermolytic decomposition of EDAB. Thermolysis of EDAB has been investigated by concomitant thermogravimetry-differential thermal analysis-mass spectrometry experiments. EDAB shows up to four H₂ d...

Based on molecular dynamics simulations, the melting points Tm of a series of 1-alkyl-3-methylimidazolium hexafluorophosphate ionic liquids [CnMIM][PF6] with n = 2, 4, 10, 12, and 14 were studied using the free energy-based pseudosupercritical path (PSCP) method. The experimental trend that the Tm decreases with increasing alkyl chain length for ILs with short alkyl chains and increases for the...
