Selective Rhodium-Catalyzed Hydroformylation of Terminal Arylalkynes and Conjugated Enynes to (Poly)enals Enabled by a π-Acceptor Biphosphoramidite Ligand

The hydroformylation of terminal arylalkynes and enynes offers a straightforward synthetic route to the valuable (poly)enals. However, the hydroformylation of terminal alkynes has remained a long-standing challenge. Herein, an efficient and selective Rh-catalyzed hydroformylation of terminal arylalkynes and conjugated enynes has been achieved by using a new stable biphosphoramidite ligand with strong π-acceptor capacity, which affords various important E-(poly)enals in good yields with excellent chemo- and regioselectivity at low temperatures and low syngas pressures.

Palladium-catalysed atom-economical synthesis of conjugated dienals from terminal acetylenes and acrolein

Conjugated (E,E)-dienals are versatile synthetic intermediates owing to their trifunctional, electrophilic nature and the prevalence of the (E,E)-diene in a wide range of functional molecules. It is shown herein that (E,E)-dienals can be readily prepared

Palladium(II) and palladium(0)-cocatalyzed ring opening and oxidation reactions of 2-(arylmethylene)cyclopropylcarbinols

In the presence of Pd(II) acetate and triethylamine as well as triphenylphosphine, 2-(arylmethylene)cyclopropylcarbinols 1 underwent ring opening and oxidation reactions smoothly to deliver (2E,4E)-5-arylpenta-2,4-dienals 2 in toluene at 60 °C in moderate

Chromium-carbyne complexes: Intermediates for organic synthesis

(Chemical Equation Presented) On the same route: Chromium-carbyne complexes are readily prepared by treatment of 1,1,1-trichloromethyl reagents with chromium(II) chloride. They serve as intermediates in the selective formation of a wide variety of products, such as alkynes, alkenes, β-hydroxy ketones, aldehydes, allylic alcohols, and allenes (see scheme, E = electrophile).

A stereoselective synthesis of unsaturated phosphonates by Wittig-Horner reactions of bisphosphonylmethane with 5-aryl-(3-methyl)-2E,4E-pentadienals

A new type of unsaturaled phosphonates 5 were synthesized by the Wittig-Horner reactions of bisphosphonylmethane 4 with 5-aryl-2(E),4(E)-pentadienal and 5-aryl-3-methyl-2(E), 4(E)-pentadienal. The structures of all new compounds prepared were characterize
