[Epub ahead of print]Tremorine and precursors of Gemini surfactants have been synthesized in one pot, three-steps, double catalytic A3- coupling reaction and characterized by structural and spectroscopic properties. Cationic [Au(I)-L1][SbF6] complex is more active catalyst compared to neutral L2 and L3- Au(I)- [bis(trifluoromethanesulfonyl)imidate] complexes (L1, L2 = Buchwald-type biaryl phosphane and L3 = triphenylphosphine) to promote the double A3- coupling of ethynyltrimethylsilane, secondary amine (cyclic, aliphatic or aromatic) and formaldehyde.
