The Alkylating Properties of Alkyl Thiophosphates

Angewandte Chemie International Edition in English, 1965
AbstractThiophosphate and phosphate esters have been synthesized in great variety since about 1945, and are being produced in increasing quantities, mainly for plant protection. An important property of alkyl phosphates and thiophosphates is their alkylating power, which is comparable with that of dialkyl sulfates and alkyl p‐toluenesulfonates.

Solution properties of alkyl glucosides, alkyl thioglucosides and alkyl maltosides

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2004
Abstract Aqueous solutions containing sugar-based surfactants, alkyl glucosides, thioglucosides and maltosides, have been investigated in a wide concentration range, at different temperatures. Colligative properties (freezing point and vapour pressure depression), volumetric, adiabatic compressibility, surface tension and calorimetric methods were ...

Alkylation of heteroaryl alkyl metals by bistrialkylsilylperoxides

Tetrahedron, 1990
AbstractHeteroalkyl methyl metals obtained from (III)/LDA undergo methylation upon treatment with the silylperoxide (I) to give the compounds (IV); in addition, the trimethylsilyloxylation products (Va) and (Vb) as well as the silylation product (VIa) are formed.

Alkylation of tricarbonylcyclohexadienyliron salts () with lithium alkyls

Tetrahedron Letters, 1980
Abstract The salts 1 (Y=H, OMe, Me) react with RLi(R=Me, n-Bu, i-Pr, t-Bu) in CH2Cl2 at low temperature to give 2 and 3 in excellent yields. Nucleophilic addition at the 1-position of 1 (Y=OMe) has been observed for the first time.

Reductive alkyl–alkyl coupling from isolable nickel–alkyl complexes

Nature
The selective cross-coupling of two alkyl electrophiles to construct complex molecules remains a challenge in organic synthesis1,2. Known reactions are optimized for specific electrophiles and are not amenable to interchangeably varying electrophilic substrates that are sourced from common alkyl building blocks, such as amines, carboxylic acids and ...
