WebThis equation is the rate law of the reaction. The proportionality constant, k, is known as the rate constant of the reaction. The rate constant depends on temperature, and more specifically it increases with it. The exponents in the rate law are integers (positive or negative) or simple fractions. These exponents are determined experimentally. WebTrimethylsilyl iodide has been demonstrated to convert alkyl esters into acids via TMS esters (Scheme 60) < 76AG(E)774, 77JA968 > and lactones to iodoalkyl esters via TMS esters < 81SC763 >. Trimethylsilyl bromide also reacts with lactones to produce the corresponding bromoalkyl TMS esters < 79AG(E)689 >. Olah et al. found that a …
