A direct evidence of the influence of aggregation state of lithiated penylacetonitrile 1 on the 1,2 versus 1,4 regioselectivity towards benzylideneacetone 2 was established. Progressive addition of hexane to THF solutions raised the aggregates proportion of 1 as evidenced by IR ν(CN) band and led to an increase of 1,4 adduct. Monomers afforded 1,2 addition in pure THF.
