Angewandte Chemie. 124:3370-3388
Palladiumkatalysierte Kreuzkupplungen versetzten Organiker in die Lage, C-C-Bindungen gezielt und unter milden Reaktionsbedingungen zu einzufuhren. Wahrend Phosphanliganden in diesen Umsetzungen am intensivsten erforscht wurden, sind seit kurzem auf

This base is just right! A new base, potassium 2,2,5,7,8-pentamethylchroman-6-oxide, for Pd-catalysed amination has been rationally designed that has sufficient basicity to efficiently deprotonate the intermediate aryl palladium ammonium complex, lea
