β-Triorganosilyl derivatives of silane- and germane-carboxylic acids are reported for the first time. Studies are reported on their spectral properties (IR, UV, PMR), acidity and thermolysis. No evidence has been found in support of extended d-orbital participation, (π → d → d)π bonding, in the ground state of the polysilanecarboxylic acids and their conjugate base forms. (d → d)π bonding may be an
首次报道了硅烷和锗烷羧酸的β-三有机甲硅烷基衍生物。研究报告了它们的光谱特性(IR,UV,PMR),酸度和热分解。在聚硅烷羧酸及其共轭碱形式的基态下,未发现支持扩展的d-轨道参与(π→ d → d)π键的证据。(d → d)π键可能是降低五苯基二硅烷羧酸热脱羰活化能的重要因素。
