Lines, Schlenk and Glovebox Techniques

Manipulations involving materials sensitive to air or water vapour can be carried out by these procedures. Vacuum-line methods make use of quantitative transfers, and P(pressure)-V(volume)-T(temperature) measurements, of gases, and trap-to-trap separations of volatile substances. 

Syringe techniques have been developed for small volumes, while for large volumes or where much manipulation is required, dryboxes (glove boxes) or dry chambers should be used. 

Titles of periodicals are defined as in the Chemical Abstracts Service Source Index (CASSI), except that full stops have been omitted after each abbreviated word. Abbreviations of words in the texts of Chapters 4, 5 and 6 are those in common use and are self evident, e.g. distn, filtd, cone and vac are used for distillation, filtered, concentrated and vacuum.

All manipulations of compounds were carried out using standard Schlenk, vacuum line, and glovebox techniques. Pentane, diethyl ether, tetrahydrofuran, and toluene... 

Since silylenes are air and moisture sensitive, the synthetic operations were carried out under an atmosphere of dry argon or nitrogen by using modified Schlenk line and glovebox techniques. Solvents THF and toluene were freshly distilled from sodium... 

The syntheses of [Ln(OR)x] are air-sensitive because of their susceptibility to hydrolysis. Therefore, most work is performed under strict anhydrous conditions using glovebox and Schlenk line techniques. While the -1-2 and -f 4 states have...
