Vinyl nosylates derived from 1,3-dicarbonyl compounds could be engaged in Suzuki-Myaura cross coupling reactions with aryl-, vinyl- and methylboronic acids or trifluoborate derivatives at room temperature in the presence of 2mol% of [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) [PdCl2(dppf)]. One-pot procedures have been set up for practical and efficient nosylation-cross-coupling reactions. Nosylate, as a cheap novel pseudo-halide, gives very stable compounds and is very efficient in Suzuki-Myaura cross coupling reactions (21 examples, 44-99%).

, p. 733 - 737 (2016/11/13)
A series of new polysubstituted derivatives of 2-tetralones possessing two ester groups were synthesized via a tandem aldol condensation-Diels-Alder-aromatization sequence of reactions. All the three steps took place in one pot and in the presence of amin
Vinyl nosylates: An ideal partner for palladium-catalyzed cross-coupling reactions

Carbonyl conjugated vinylic selenides undergo 1,3 and 1,5-carbonyl transposition sequences through organometallic reagents addition reactions followed by acid hydrolysis.
Condensation reactions in water of active methylene compounds with arylaldehydes. One-pot synthesis of flavonols
Fringuelli, Francesco,Pani, Giosanna,Piermatti, Oriana,Pizzo, Ferdinando
, p. 11499 - 11508 (2007/10/02)
The condensation reactions of acetophenone, cyclohexanone, isophorone, phenylacetonitrile, p-nitrophenylacetonitrile, (phenylsulfonyl)acetonitrile and indene with benzaldehyde were studied in water heterogeneous phase in the presence and absence of anionic and cationic surfactants such as SLS, CTACl, (CTA)2SO4 and CTAOH. All the reactions occur with excellent yields. The cationic surfactants favour the reaction and the comparison with the corresponding tetrabutylammonium salts show that the micellar catalysis is effective mainly towards the dehydration reaction following that of condensation. Anionic surfactant SLS is inactive. 2'-hydroxychalcones were prepared in aqueous medium in good-excellent yields and the one-pot synthesis of 7- and 3',4'-substituted flavonols was achieved.
