Substituted 1,2-Diborylalkenes - Preparation and Photoisomerization

The organo(halo)substituted cis-1,2-diborylalkenes cis-R2BC(R)=C(Et)BEt2 (Z)-1 to (Z)-14 are prepared CR> and ClBR2; route II from cis-R3SnC(R)=C(Et)BEt2 and RnBHal3+n, n = 0-2; (Z)-11 (route III): cis-ClB(Ph)CH=C(Et)BEt2 and Me3SiOMe>.Their 11B- and 13C-NMR data show the degree of pz(B)/(C=C) ? overlap and are compared with the corresponding data of the monoboryl alkenes ; the cis-2-boryl-1-silylalkenes , and the cis-2-boryl-1-stannyl-alkenes . - Compounds (Z)-3, (Z)-4, (Z)-9, (E)-18, and (E)-19 with one or two nearly coplanar pz(B) and pz(C=C) groups (pl-R2B) are isomerized by UV irradiation to their equilibria with the corresponding trans isomers (E)-3, (E)-4, (E)-9, (Z)-19, resp., with one or two nearly orthogonal pz(B) and pz(C=C) groups (or-R2B).Irradiation of (Z)-9 gives the isomer pair (Z/E)-iso-9 by a Ph/Et exchange between the two boron atoms.Key Words: cis-1,2-Diborylalkenes, organo-, halosubstituted / cis/trans 1,2-Diborylakenes, organosubstituted, photoisomerization of / cis/trans-2-Boryl-1-silylalkenes, organosubstituted, photoisomerization of / Diorganoboryl groups of alkenes, or- and pl-B(pz)orbitals / Monoborylalkenes, organosubstituted
