Calcium-catalyzed friedel-crafts alkylation at room temperature
Niggemann, Meike,Meel, Matthias J.

Chemical Equatation Representation A novel calcium catalyst was found to efficiently functionalize electron-rich arenes with secondary and tertiary benzylic, propargylic, and allylic alcohols under very mild reaction conditions. The new catalyst system significantly enlarges the scope of the reaction, which was previously limited except for the few examples with secondary benzylic alcohols.
Gold(I)-catalyzed intermolecular hydroarylation of allenes with nucleophilic arenes: scope and limitations
Tarselli, Michael A.,Liu, Ann,Gagné, Michel R.
experimental part, p. 1785 - 1789 (2009/06/28)
The addition of nucleophilic methoxyarenes to allenes proceeds at room temperature in dichloromethane with a catalytic amount of phosphite-gold(I) precatalyst and silver additive. The addition is regioselective for the allene terminus, and generates E-all
REGIOSELECTIVE PRENYLATION OF PHENOLS BY PALLADIUM CATALYST: SYNTHESES OF PRENYLPHENOLS AND CHROMANS

The palladium-catalyzed coupling reaction of iodophenols (1) with 2-methyl-3-butyn-2-ol gave alkynylphenols (2).Catalytic hydrogenation of 2 over Raney nickel and the subsequent dehydration of the resultant alkylphenols (3) gave regioselectively the desired prenylphenols (4).Dehydration of alkylphenols (3f-h) gave chromans (7).
