Benzylic zinc reagents prepared by direct insertion of zinc to benzylic chlorides in the presence of LiCl undergo smooth cross-coupling reactions with aromatic chlorides, bromides and tosylates using Ni(acac)(2) and PPh(3) as a catalyst system.
In a previous article (1)) on the secretion of gastric juice in fever, it was reported that the concentration of’ chlorides in gastric juice was constant or slightly reduced. In this present paper I wish to emphasize the relation between the secretion of total chlorides in gastric juice and the secretion of free hydrochloric acid. Most of the data for this paper were obtained at that time but u...
The blood findings in five monkeys after experimental high intestinal obstruction are reported. All animals showed the marked rise in non-protein nitrogen characteristic of intestinal obstruction in man and the dog. Two monkeys showed a very marked drop in chlorides, the others a less marked fall. Coincident with the change in chlorides there is a rise in the CO(2)-combining power. The uric aci...
in the 1980’s, medium-chain acyl-coa dehydrogenase deficiency (mcadd) was first described in the literature as three children who presented with coma, hypoglycemia, hyperammonemia, and fatty liver while fasting. these symptoms while similar to reye’s syndrome, were found to be due to an inability to metabolize medium chain fatty acids during fasting periods. fatty acids are utilized by the body...
Chemical studies of the blood and urine of four dogs following pyloric obstruction are reported. The observations of other workers that a fall in chlorides and a rise in CO(2)-combining power of the plasma occur, are confirmed. There is also a marked rise in the non-protein nitrogen of the blood, consisting mainly of urea nitrogen and undetermined nitrogen. The fall in chlorides is not due to t...
1. In acute experimental hydronephrosis chloride retention occurs as well as retention of water, urea, and phenolsulfonephthalein. 2. If both water and chlorides are retained there may be no appreciable rise in the plasma chloride content. 3. When chlorides are retained, but not water, the chloride content of the plasma rises strikingly. 4. After the removal of the ureteral obstruction in acute...
An efficient and practical protocol for palladium-catalyzed decarboxylative arylation of imidazo[1,2-a]pyridine-3-carboxylic acids with aryl chlorides has been developed. Note that the reaction could proceed smoothly without an additive in aqueous medium under an ambient atmosphere, and the addition of H2O could effectively promote the decarboxylative arylation. Particularly noteworthy is that ...
The first method for achieving alkyl–alkyl Suzuki reactions of unactivated secondary alkyl chlorides has been developed. Carbon–carbon bond formation occurs under mild conditions (at room temperature) with the aid of commercially available catalyst components. This method has proved to be versatile: without modification, it can be applied to Suzuki reactions of secondary and primary alkyl bromi...
