The catalytic activity of iodine monobromide and iodine monochloride were investigated in the reaction, Et,SiOBu" + Bu'OH Et,SiOBus + Bu"0H. Pseudo first-order rate constants were measured by gas chromatography, at lo", 20", 30", and 40ยฐC for iodine monobromide and at lo", 20", and 30ยฐC for iodine m

โฆ Synopsis
The kinetics of the eledrophilic substitution of several trialkyltin chlorides by iodine monochloride are presented. Rate constants have been determined at four different temperatures and the activation parameters A, En, and AS"= are calculated. A mechanism is proposed involving charge-transfer as the driving force for the substitution. 0 1993 John Wiley &. Sons. Inc.

Kinetics of oxidation of thiocyanate ion (NCS-) by iodine monochloride and iodine has been studied in aqueous perchloric acid medium. The rates of oxidations followed the rate laws: Variations in ionic strength and dielectric constant of the medium had little effects on the rates of reactions with
Four different grades of pitch-based graphite fibers (Amoco P-55, P-75, P-100, and P-120) were intercalated with each of four different intercalates: bromide (Br,), iodine monochloride (ICI), copper(I1) chloride (CuCI,), and nickel(H) chloride (Nit&). The P-55 fibers did not react with Br? or Nit&,
The use of iodine monochloride (IC1) as a thermal source of chlorine atoms in known concentration is discussed with particular reference to the suppression, by large excesses of iodine, of the chain processes normally associated with chlorine atom reactions. The kinetics and mechanism of the reactio
