1-Alkylpyridinium bromides 1 having activated N-methylene group react with phosphorus trichloride to give N-(dichlorophosphinomethylene)pyridinium ylides 2.

Large bathochromic shifts are observed in the visible spectrum of zinc oxinate in anhydrous chloroform on the addition of heterocyclic nitrogen bases (pyridine and its methyl derivatives).These shifts as compared to those due to solvent effects alone have been attributed to adduct formation.The shifts are accompanied by a simultaneous increase in the absorbance values.From a quantitative evaluation of this data, the adduct formation constants of what proved to be 1:2 chelate-nitrogen base adducts in most cases have been determined.A monoadduct of the lowest adduct formation constant is obtained with 2,6-lutidine.The stabilities of these adducts increased in the following order: 2,6-lutidine < 2,4,6-collidine < 2,4-lutidine < 2-picoline < pyridine < 3-picoline < 4-picoline.The stabilities seem to increase in accordance with the Lewis acid-base concept and the role of steric factors has been elaborated.The adducts except that of 2,6-lutidine possess hexa-coordinated octahedral structures.

The flavour of a typical sample of Gruyere cheese and that of a Gruyere exhibiting a potato-like off-flavour was examined by instrumental and sensory analyses. Based on the results of dynamic headspace gas chromatography-mass spectrometry (DHGC/MS), aroma extract dilution analysis (AEDA) and gas chromatography-olfactometry of static headspace samples (GCO-H), 2-/3-methylbutanal, methional, dimethyltrisulphide, phenylacetaldehyde, 2-ethyl-3,5-dimethylpyrazine, 2,3-diethyl-5-methylpyrazine, methanethiol, as well as butyric, 2-/3-methylbutyric and phenylacetic acid form the typical flavour of Gruyere cheese. The potato-like character of the sample showing an aroma defect, however, could not be attributed definitively to one of these compounds. Considering the results of DHGC/MS and AEDA, 2-ethyl-3,5-dimethylpyrazine and 2,3-diethyl-5-methylpyrazine could be the possible causes of the off-flavour.

Starting from a formula of Gaw and Scott, we show by a scaling argument that the volume-composition isotherm of a binary liquid mixture at its consolute temperature should be of the same algebraic degree at the consolute point as the volume-composition coexistence curve and , by continuity, tangent to it there.Our data on 2,4-lutidine + water, and our data together with those of Woermann and Sarholz on isobutyric acid + water, show conspicuously the non-classical vanishing of the curvature of the volume-composition critical isotherm at the consulte point.The predicted tangency of the critical isotherm and coexistence curve is confirmed for isobutyric acid + water within the uncertainties in the estimates.
