Top Picks: new discover of 4265-25-2

Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C9H8O, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 4265-25-2

Rates of cleavage of RCH2SiMe3 by 2.00M-NaOMe in MeOH or MeOD at 50 deg C have been determined for R = furan-2-yl, 2-thienyl, benzofuran-2-yl, and benzothiophen-2-yl; the values of 1E5ks in MeOH and (in parentheses) in MeOD, where ks is the specific second order rate constant, are, respectively: 0.070 (0.167), 0.26 (0.52), 165 (310), and 70 (130) dm3 mol-1 s-1.The values of the ratios of ks in MeOH to hat in MeOD are in the range 0.42-0.54, consistent with rate-determining separation of the carbanion RCH2-. The results are discussed in the light of the deprotonation energies calculated (STO-3G) for the corresponding carbon acids RCH3, and approximate pKa values are derived for the latter, viz. (R =) furan-2-yl, 40.6; 2-thienyl, 39.7; benzofuran-2-yl, 35.2; benzothiophen-2-yl, 35.8.
