- W2140169969 abstract "Abstract The reaction of the (dichloromethyl)oligosilanes R(Me 3 Si) 2 SiCHCl 2 4a − d ( 4a : R = Me; 4b : R = t Bu; 4c : R = Ph; 4d : R = SiMe 3 ) with 8‐(dimethylamino)‐1‐naphthyllithium leads to the intramolecularly donor‐stabilized silenes 1a − d . Whereas 1a , b , and d were isolated as thermally stable yellow crystalline compounds, 1c could not be separated in a pure form but was characterized by NMR spectroscopy and mass spectroscopy as well as by its chemical reactivity with a variety of substrates. Dynamic 1 H NMR spectroscopic studies of 1a and 1d revealed coalescence of the signals of the two CSiMe 3 groups. In agreement with theoretical calculations, this effect was interpreted as the result of internal rotations about the silene double bond. These findings and the known relatively long Si=C distances for 1d , 2 and 3 help establish the ylide‐like nature of the silenes prepared. Treatment of 1a − d with water produced the silanols 9a − d . Treatment of 1a , b , and d with methyl iodide caused a rearrangement of the silenes, one methyl substituent formally migrating from the coordinated dimethylamino group to the silene carbon atom producing the respective cyclic aminosilanes 11a , b , and d . As the outcome of the reaction of 1d with benzaldehyde, 2,2‐bis(trimethylsilyl)vinylbenzene ( 14 ) and a mixture of the two isomers of the cyclodisiloxane 13 were obtained.
