Organosubstituted 2,5-Dihydro-1,2,5-oxoniasilaboratoles - Characterization and Reactivity

The potassium salt of the anions , prepared from the organosubstituted cis-2-boryl-1-silylalkenes 1a-d and KOH, react with the electrophiles R1Hal IV: ClElIV(CH3)3, ElIV = Si, Ge, Sn, Pb> to give the neutral five-membered ring compounds .On heating of 3H or 3Sn either ethyl migration occurs to yield the saturated diasteromers , or elimination of ethane takes place to give the unsaturated compounds .The reaction of 2 with ClPb(CH3)3 leads to 3Pb (11B-NMR), which exclusively form 5 with elimination of C2H5Pb(CH3)3.
