A compound made from eicosatetrayne and mercuric chloride is further polymerized using a cuprous chloride/pyridine solution. Organo-arsenic polymers are made from the reaction product of the dilithioderivative of a diethynyl benzene with phenyl di-iodoasine, by taking this product and treating it ...

The word Arsenic is derived from an Arabic word,al-zarnikh, and Professors Hantszch and Widman decided that all heterocyclic compounds using arsenic should begin with ‘ars’. (Other elements gave rise to prefixes like ‘fluor’ for fluorine and ‘iod’ for iodine and so on.) So far so ...
The mechanism by which sulfur is able to extract copper from its compounds is obscure. However, a similar observation has been made for arsenic [18]. The phenomenon of sulfur “extracting” copper from any of its compounds recalls the somewhat analogous reaction of Acknowledgements The authors ...
In alternative embodiments, the doping additives are H2D(tBu), HD(tBu)2, D(tBu)3, D(SiH3)3, D(Si2H7)3, HD(Si2H7)2, D(Si3H10)3, HD(Si3H10)2, H2D(Si3H10), D(Si4H13)3, HD(Si4H13)2, H2D(Si4H13), B10H14 hydride, elemental boron, elemental phosphorus, elemental arsenic,...
To a suspension of 2 g of 2-methyl-3-nitroaniline and 1.02 g of arsenic(V) oxide hydrate are added 2.88 mL of glycerin followed by 1.09 mL of concentrated sulfuric acid. The resulting black slurry is stirred at about 150° C. for 4 hours. The black oil is cooled to room temperature...
Tetra-cysteine tagged proteins can be assayed using the bi-arsenical-tetra-cysteine detection method (Zhang et al., 2002, Nar. Rev. Mol. Cell. Biol. 3, 906-918) Autophagocytosis inducers identified using the methods of the invention can be used to prepare pharmaceutical compositions useful ...
