Fig. 4: Reaction of ytterbium alkyls with benzene.
From: Hydroarylation of olefins catalysed by a dimeric ytterbium(II) alkyl

The addition of benzene to compound 3 at room temperature provides ethylbenzene and the ytterbium deuteride complex 2-d. The addition of benzene to compound 4 at room temperature provides n-propylbenzene and the ytterbium deuteride complex 2-d.
