Organoaluminum palladium

E. Cross-coupling Reactions of Organoaluminum or Organozirconium Compounds in the Presence of Nickel or Palladium Catalysts... 

The palladium-catalyzed systems seem quite flexible with regard to the nature of the organoaluminum, since aJkyl-, alkenyl- and alkynyl-aluminum reagents were used successfully (entries 8-14, Table 18). Furthermore, the acyl chloride substrates include alkyl, aryl and alkenyl substituents. 

Table 18 The Palladium-catalyzed Addition of Organoaluminums to Acyl Chlorides (equation 23)...

Organoaluminum compounds undergo the coupling reaction with acyl chlorides in the presence of palladium catalyst Not only alkyl-, alkenyl-, and alkynylalanes bnt also alkenylalanates are used for the reaction. This reaction can also proceed in the absence of palladium catalyst, but the stereoselectivity is much better when the reaction is catalyzed by palladium (Scheme 11). ... 

The first carbonylative coupling of organoaluminum compounds appeared in 1985. Beletskaya and colleagues [88] demonstrated that ketones are produced in good yields by a palladium-catalyzed reaction of arylaluminium compounds with aryl iodides in the presence of CO (Scheme 4.49). That same year, the...
