Alkyl bis(trichloro-t-alkyl) phosphites
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19671. As a result of steric hindrance the reactivity of bis(trichloro-t-alkyl) phosphorochloridites toward alcohols diminishes from primary to secondary alcohols, and with tertiary alcohols the reaction does not go. 2. Alkyl bis[1-methyl-1-(trichloromethyl)propyl], alkyl phenyl 2,2,2-trichloro-1,1-dimethylethyl, and dialkyl 1-methyl-1 ...

Alkylation of metals and the activity of metal‐alkyls†
Toxicological & Environmental Chemistry, 1984The biochemical basis for resistance to metal ion toxicity is emerging though it is complicated by the different resistance mechanisms. Several strategies for resistance to toxic metal ions have been identified: The development of energy driven efflux pumps which keep toxic element levels low in the interior of the cell.

Alkylation of germanium halides by aluminium alkyls
Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1967The alkylation of germanium tetrachloride by trimethylaluminium, methylaluminium sesquichloride, triethylaluminium, and tri-isobutylaluminium has been examined. Tetra-alkylgermanes are formed together with di- and poly-germanes, GenR2n+2. In all cases the monoalkylation of GeCl4 is slow, and the formation of reactive Ge·Al intermediates is postulated ...

The introduction of alkyl chains to the periphery of the conjugated skeleton of organic chromophores is generally to improve their solubility. However, a number of investigations show that the length of alkyl chains could affect significantly the solid ...

The reaction of alkyl radicals with alkyl diphenylphosphinites
Tetrahedron, 1969Abstract Methyl and i-propyl radicals have been found to react with methyl diphenylphosphinite to give respectively, methyldiphenylphosphine oxide and i-propyldiphenylphosphine oxide. t-Butyl radicals under similar conditions, initiated the transformation of the ester to methyldiphenylphosphine oxide.

Bulletin du cancer, 2011
With the approval of mechlorethamine by the FDA in 1949 for the treatment of hematologic malignancies, alkylating agents are the oldest class of anticancer agents. Even though their clinical use is far beyond the use of new targeted therapies, they still occupy a major place in specific indications and sometimes represent the unique option for the ...
