Fluorescence Studies on Morphological Change of Oil-in-Water Microemulsions upon Dilution with Water

The morphological change of oil-in-water microemulsion (ME) has been studied by steady-state and time-resolved fluorimetry.The standard ME (ME1) consisted of sodium hexadecyl sulfate (7.2percent wt/wt), pentanol (10.8percent), hexadecane (2.7percent), and water (79.3percent).The fluorescence quenching of pyrene by N,N-dihexylaniline was used as a probe reaction.Both nonlinear Stern-Volmer relationship and nonexponential fluorescence decay curves of the pyrene monomer in ME containing the quencher were analyzed by Poisson statistics, which revealed that ME is subdivided upon dilution with water.

TERMINATION RATES BY TIME-RESOLVED ESR. THE N-HYDROPYRIDINYL RADICAL IN SOLUTION AND THE INFLUENCE OF NON-UNIFORM RADICAL CONCENTRATION ON THE APPARENT RATE CONSTANT.

The rate constants (2k) for the second-order self-termination reaction of the N-hydropyridinyl radical have been measured by time-resolved ESR during intermittent UV photolysis of pyridine in various solvents containing propanol(-2). The frequency factor and the activation energy are (1. 8 plus or minus 0. 4) multiplied by 10**1**0 M** minus **1 s** minus **1 and (10. 7 plus or minus 0. 4)kJ multiplied by mol** minus **1, respectively, in propanol(-2)/acetone (1:1 by volume) as obtained from the Arrhenius plot of 2k in the temperature range between 293 and 230 K. A model is presented for the correction of the influence of non-uniform radical concentration on apparent values of second-order rate constants as determined by time-resolved ESR during intermittent photolysis.

Silver-promoted benzannulations of siloxyalkynes with pyridinium and isoquinolinium salts

We describe the development of efficient benzannulations of siloxyalkynes with pyridinium and isoquinolinium salts. Such reactions are successfully promoted by a stoichiometric amount of silver(I) benzolate under mild reaction conditions. This process proceeds via a formal inverse-electron demand Diels-Alder reaction, followed by fragmentation of the initially produced bicyclic adducts to deliver a range of synthetically useful phenols and naphthols.

A Quantitative Description of Polarity of Binary Solvent Mixtures Using Different Polarity Scales

The solvent polarities of 12 binary mixtures have been examined using 6 polarity scales as a function of their composition.They are quantitatively described by a simple, closed form, two-parameter equation which can explain e.g. deviations from linear correlations of polarity scales for mixtures.
