The relative nucleophilicity of chloride, bromide and iodide anions in [bmim][BF4] ionic liquid has been measured by studying their reaction with methyl p-nitrobenzenesulfonate ([bmim] = 1-butyl-3-methylimidazolium cation). It has been found that iod

The solvolysis of 4-methoxybenzyl chloride (1) and bromide (3), and 1-(4-methoxyphenyl)ethyl chloride (4) in a variety of solvents were carried out. The observation of linear correlation using the dual-parameter Grunwald–Winstein equation, and the

For the methanolyses in acetonitrile at 25.0 °C of benzoyl chloride and eleven para- or meta-substituted derivatives, the kinetics of methyl ester formation have contributions both first-order and second-order in methanol. The Hammett plots for the

The reaction of oct-4-yne with 20% trifluoroacetic acid and a variety of relatively weak nucleophiles in methylene chloride was found to produce a mixture of anion incorporated and solvent incorporated products. The rates of these reactions with a ra

It has been shown that 1,8-dichloro-1,8-dimethyl-1,8-digermacyclotetradecane transports chloride anion more effectively than bromide anion in a U-tube test. The dibromo analogue also can transport anions. The efficiency of transport of open chain ana

Trinorborn-1-yl phosphite has been prepared and has been shown to give highly stable phosphonium salts in its reactions with iodomethane and with a number of α-halogenoketones. Phenacyl bromide and p-bromophenacyl bromide underwent reaction at room

Electron paramagnetic resonance spectroscopy has been used to probe the anion radicals formed by electron capture by p-nitrobenzyl and p-nitrobenzylidene halides and their subsequent decomposition to yield radicals. In the case of the monohalogenated

X-Ray crystallographic studies have shown that the imidazolinium group in 2-(2-methoxy-2,3-dihydro-1,4-benzodioxin-2-yl)-4,5-dihydroimidazolium bromide (4), (+)-2-(2-methoxy-2,3-dihydro-1,4-benzodioxin-2-yl)-4,5-dihydroimidazolium hydrogen dibenzoylt

The reaction of the bromide (Me3Si)2C(SiMe2OMe)(SiPh2Br)(1) with AgBF4 in Et2O is found to give a 4:1 mixture of the rearranged fluoride (Me3Si)2C(SiMe2F)(SiPh2OMe) and the unrearranged (Me3Si)2C(SiMe2OMe)(SiPh2F). The 1,3 Si–Si migration of the OM
