  abstract  = {The synthesis and the thermal behaviour of the (methylphenylsilyl)methyl carbonates \(CH_3(C_6H_5)Si(H)CH_2OC(O)X (6: X = OCH_3; 7: X = Cl; 8: X = N(CH_3)_2)\) is described. 8 rearranges in toluene solution at 100 °C quantitatively to give the carbam oyloxysilane \(C_6H_5(CH_3)_2SiOC(O)N(CH_3)_2\) (11), whereas neat 6 and 7 at 135 °C undergo quantitative formation of \(C_6H_5(CH_3)_2SiOCH_3\) (12) and \(C_6H_5(CH_3)_2SiCl\) (13), respectively. The formation of 12 and 13 is explained by a rearrangement reaction (by analogy to the rearrangement of 8), follow ed by a decarboxylation. The thermally induced transformations 6 →12, 7 →13, and 8 →11 were found to be first-order reactions with half-lifes of ~2.6 h (135 °C, neat), ~4.5 h (135 °C, neat), and ~3.7 h (100 °C, in toluene), respectively.},

  abstract  = {IS neue C/Si-Analogenpaare (C-Verbindungen und sila- bzw. disila-substituierte Derivate), die sich strukturell vom Nifedipin ableiten, wurden synthetisiert. Diese und einige weitere C/Si-Paare wurden hinsichtlich ihrer physikochemischen und pharmakologischen Eigenschaften vergleichend untersucht. Mittels reversed-phase-D{\"u}nnschichtchromatographie wurde gezeigt, daß die Sila- bzw. Disila-Analoga lipophiler sind als die entsprechenden C-Verbindungen. Bez{\"u}glich der spasmolytischen in vitra-Aktivit{\"a}ten zeigen die Si-Verbindungen in erster N{\"a}herung {\"a}hnliche Struktur-Wirkungs-Beziehungen wie ihre Carba-Analoga. Dagegen konnten hinsichtlich der ill vlva-Effekte (cardiovascul{\"a}re und antihypertensive Aktivit{\"a}t) in einigen F{\"a}llen große Unterschiede nachgewiesen werden.},
