Hydrocarbon-soluble β-diketiminato phenylcalcium derivatives, which display various modes of Ca−μ2-Ph−Ca bridging, are accessible from reactions Ph2Hg and [(BDI)CaH]2. Although the resultant compounds inert toward C−H bonds benzene, they yield selective uncatalyzed biaryl formation when reacted with readily available aryl bromides.

A new family of readily available, recoverable and soluble polymer-monophosphite ligands were prepared and successfully used in the Rh-catalyzed asymmetric hydrogenation of enamides and beta-dehydroamino acid esters, in which up to 99 and 99.9% ee were obtained, respectively.

A series of various readily water soluble esters were synthesized by a very efficient procedure. These compounds can be useful as thermosensitive tracers for studying the cooling progress in a low enthalpy georeservoir exploitable by double flash geothermal power plant systems. The kinetics of their hydrolysis was investigated. Acylation of primary alcohols or phenols was carried out by a metho...

1. Soluble ATPase (adenosine triphosphatase) activity is released when rat liver submitochondrial particles are shaken with chloroform, provided that ATP or glycerol is present in the suspending medium. The extraction is very rapid and appears to be complete. 2. The ATPase of the chloroform extract is about 50% pure and can be readily purified to a specific activity of 60-70mumol/min per mg of ...

In this series, we herein present our research on the physiology and usefulness of Branched-Chain Amino Acids. As often presented in the preceding issues of the journal, of the nine essential amino acids, valine, leucine and isoleucine, which have branched side chains, are called Branched-Chain Amino Acids (BCAAs). BCAAs play important roles, particularly during exercise and in the maintenance ...

The alkyl fluorophosphonate grou,p of composunds has attracted much attention recently, and its most active member, di-isopropyl fluorophosphonate, has now been the subject of some published work. The substance has the formula given below. It is a clear colourless liquid, purified by redistillation, slightly soluble in water, but readily soluble in organic solvents. Aqueous solutions are unstab...

Aggregation of poly(para-phenyleneethynylene)s is efficiently suppressed by introduction of branched oligoethyleneglycol side chains rendering the polymer backbone, which is readily obtained using an A2 + BB' polycondensation protocol, soluble and highly emissive in aqueous environments.

clinically useful nitrosounea derivative (32); it is readily soluble in alcohol, and its results in coborectal cancer approximated those obtained with MeCCNU, the best nitrosourea agent for this particular type of tumor (28). We did not use MeCCNU because this drug cannot be dissolved easily in a variety of solvents (15). cis-Acid is a new water-soluble nitrosourea (30) that was shown by Corbet...

in preparation 96 4 Abstract Cyclin-dependent kinase 5 (Cdk5) functions in many neuronal processes and has recently been implicated in homeostatic plasticity. Cdk5 activation results in reallocation of synaptic strength, including weakening of some connections while strengthening others. The molecular mechanisms underlying these phenomena are thus far not understood. We show that Cdk5 phosphory...
