✦ Synopsis

ions, here on a partly positive boron atomby C-Si hyperconjugation (resonance formulas C, C')." 31 We consider the C-Si hyperconjugation to be the main reason for the B-C double bond in 6b being very short in spite of weaker n-bonding (resonance formula A).['51 The electronic stabilization of the B -C double bond by the silyl groups might also contribute to the easy formation of 4 and 6. In addition, the steric requirements of the silyl substituents contribute decisively to the kinetic stability of these methyleneboranes.
