The first example of sila-Morita-Bayis-Hillman reaction between 1-silylcyclopropenes and carbonyl compounds has been demonstrated. This novel phosphine-catalyzed transformation features a 1,3-Brook rearrangement/elimination cascade and provides convenient access to a variety of 1-(silyloxymethyl)cyclopropenes, which are not easily available via traditional methods.
Novel Organogermanium Compounds via Metalation of 3-Trimethylsilyl-3-ethoxycarbonylcyclopropene Derivatives
Preparation and full spectroscopic characterization of novel trimethylgermyl derivatives of 3-trimethylsilyl-3-ethoxycarbonylcyclopropenes (4-7) and 1,1-bis(trimethylgermyl)-3-trimethylsilyl-3-ethoxycarbonylallene (8) are described.

The synthesis of 3-substituted-3-(trimethylsilyl)cyclopropenes (X = CO2Et, CHO, CN) is described. Their acid sensitivity and thermal stability was probed and the reaction products were identified. In one case, a novel rearrangement to a Dewar furan maybe involved and this pathway was explored via kinetics and computations.
