, p. 1491 - 1494 (2007/10/03)
Contrary to literature consensus, the McMurry olefination reaction can be extended to the direct synthesis of sterically encumbered tetrakis(2- substituted) tetraphenylethenes from the corresponding 2,2′-disubstituted benzophenones. The reaction exploits
Carbocations, Carbanions, and Carbenes as Ring Members of Crown Ethers
Itter, Franz-Albert von,Voegtle, Fritz
, p. 2300 - 2313 (2007/10/02)
Di- and triarylmethyl crown ethers containing carbocations (3a,b), carbanions (4a - c), and carbene centers (5) are synthesized.Starting with the benzophenono crown 2a, the carbinols 8a,b and the carbenium ligands 3a,b were prepared.Their thermodynamic st
