Abstract: Abstract: Three-component reactions of aldehydes, amines and diethyl phosphite are efficiently catalyzed by ytterbium perfluorooctanoate [Yb(PFO)3] under solvent-free conditions, giving the corresponding α-aminophosphonates in good to excellent yields. The catalyst can be recovered and reused for several times without any significant loss of activity. Furthermore, a possible mechanism for this transformation is also presented.

Abstract: Abstract: One-pot three-component synthesis of 1,8-dioxo-9,10-diaryl-decahydroacridines in water was efficiently realized in the presence of the Brønsted acidic imidazolium salts containing perfluoroalkyl tails in good yields. The method provided several advantages such as low catalyst loading; recycle of the catalyst and simple work procedure. [Copyright &y& Elsevier]
