OrganosubstitutedBicyclic and Monocyclic Compounds from 2,5-Dihydro-1,2,5-oxasilaboratolates1a)The potassium salts of the cyclic anions of (A: R, R′ = CH3; B: R = C2H5, R′ = CH3; C: R = C6H5, R′ = CH3 react with [(CH3)2NCH2]Br in THF to yield the bicyclic compounds 1a (X-ray crystal structure analysis), 1b/1b' (endo/exo-C2H5), and 1c/1c' (endo/exo-C6H5). D (R=CH3, R'=C6H5) reacts with [(CH)32NCH2]Br to form a 1:4 mixture of 1d together with the heterocycle (3d) with elimination of (CH3)2N-C3H7. - From A - D and CIP(C6H5)2 the six-membered heterocycles (2a-d) are obtained in yields of ca. 90%.
