Hexamethyl phosphoric acid triamide

The first attempts to control a synthetic process using multifunctional monomers were published in 1967/68 by Stille and co-workers [9-12]. They condensed 2,5-disubstituted 1,4-benzoquinones 2 with various tetra-functional aromatic compounds 1 containing amino-, hydroxy- and chloro- functionalities. When carrying out the reaction at high tanperature in polar, aprotic solvents such as HMPT (hexamethyl phosphoric acid triamide) they immediately ob-... [Pg.3]

Ester Enolates Quite different is the situation when ester enolates are used as nucleophiles. The yields obtained are generally low, and it is assumed that nonstabilized carbanions attack the metal in preference to the aUyl group [110], resulting in reduction of the complex rather than alkylation. However, addition of hexamethyl phosphoric acid triamide (HMPA) to this reaction completely suppresses the reduction and permits the alkylation to proceed with nonstabilized carbanions as well [111]. For example, treatment of tt-allylpalladium chloride with... [Pg.950]

Electrolyte solution is formed according to eq. [9.7]. Conductivity is a distinctive feature of any material. The practice of application of individual and mixed solvents refers to electrolyte solutions, having conductivities > 10 Cm/m. Binary systems, such as carbonic acids-amines, cresol-amines, DMSO-carbonic acids, hexamethyl phosphorous triamide acids, and aU the systems acids-water, are the examples of such solvents. [Pg.508]
