The synthesis of 1,1-bis(4-hydroxyphenyl)-2-phenylethylene, which is of biological interest, has been reported by several authors in the past. In this article an improved method is introduced. Also a protective group which is easily attached and remo

ChemInform Abstract: Di-π-methane-Like Photorearrangements of α,β-Unsaturated Organoboranes in the Synthesis of Borirenes and Boracarbenoid Intermediates

Autor: Babak Shafii, Marek P. Boleslawski, John J. Eisch

Publikováno v: ChemInform. 22

The photoisomerization of a,P-unsaturated organo- boranes, either as the neutral coordination complex with tertiary amines (R3B.NR,') or as the anionic complex with organoalkali compounds (R4B-), leads, via a 1,a-shift of organic groups from boron to

Bora-aromatic systems. 12. Thermal generation and transformation of the borepin ring system: a paradigm of pericyclic processes

Autor: Arnold L. Rheingold, John J. Eisch, James E. Galle, Babak Shafii

Publikováno v: Organometallics. 9:2342-2349

The overall conversion of borole to this isomer of borepin involves a remarkable sequence of pericyclic reactions: a Diels-Alder cycloaddition, 1,3-sigmatropic suprafacial rearrangements of the resulting 7-borabicyclo[2.2.1]heptadiene, a 1,6-disrotat
