Ph3La⋅5 LiCl and the related (m‐xylyl)3La⋅5 LiCl were used as Hal/La exchange reagents (Hal=Br, I) for the preparation of various triaryl‐ and triheteroaryl‐lanthanum derivatives. These new exchange reagents are compatible with isoquinolines and some functional groups such as a nitrile or an ester. The reactivity of the resulting lanthanum compounds towards electrophiles, such as ketones, aldehydes
