摘要：

For the reaction of various silyl-lithium compounds with tetrahydrofuran (R3SiLi + C4H8O → R3Si· CH2·CH2-CH2·CH 2·O-Li+) the thermodynamic constants of activation at 30° for Ph3SiLi, MePh2SiLi, and Me 2PhSiLi respectively are: ΔG‡ 26.7, 26.1, and 26.4 kcal. mole-1: ΔH‡ 22.6, 15.1, and 19.0 kcal. mole -1 ΔS‡ -13.6, -36.5, and -24.5 cal. deg.-1 mole-1.
