4-Benzylidene-5-oxazolones 5 do not react with P(OMe)3; with P(NMe2)3 they give rise to 4-α-benzyl-5-dimethylaminooxazoles 6.This behavior differs from that of the corresponding pyrazolones and isoxazolones and is attributed to a decreased stability of the dipolar adduct resulting from a β attack of phosphorus.
