Nickel-Catalyzed Hydroalkynylation of 1,3-Dienes with Simple Alkynes

Abstract

A hydroalkynylation reaction of 1,3-dienes with simple alkynes, facilitated by an efficient nickel catalyst system with the 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (Xantphos) ligand, is presented. This reaction displays a broad substrate range for alkynes, encompassing both aryl alkynes and alkyl alkynes, thereby overcoming previous constraints in 1,3-diene hydroalkynylation. The method offers a convenient and direct means for obtaining allylic alkynes with high atom and step economy.

Key words

nickel catalysis - hydroalkynylation - dienes - alkynes - regioselectivity

• 16 1,1′-[(1E)-3-Methylpent-1-en-4-yne-1,5-diyl]dibenzene (3a); Typical Procedure: In an N₂-filled glove box, an oven-dried sealed tube equipped with a stirrer bar was charged with Ni(COD)₂ (2.8 mg, 0.01 mmol) and Xantphos (11.6 mg, 0.02 mmol). THF (1 mL) and H₂O (2.0 mmol) were injected into the tube, and the solution was stirred at 25 °C under N₂ for 1 min. (E)-1-Phenyl-1,3-butadiene (1a; 39.0 mg, 0.3 mmol) and phenylacetylene (2a; 10.2 mg, 0.1 mmol) were then successively introduced into the system. The tube was sealed with a Teflon-lined screw cap and removed from the glove box, and the mixture was stirred at 60 °C for 12 h, then cooled to r.t. The resulting mixture was concentrated and the residue was purified by column chromatography (silica gel, pentane) to give a colorless oil; yield: 16.0 mg (0.069 mmol, 69%). ¹H NMR (400 MHz, CDCl₃): δ = 7.50–7.44 (m, 2 H), 7.41 (d, J = 7.2 Hz, 2 H), 7.37–7.28 (m, 5 H), 7.24 (d, J = 7.1 Hz, 1 H), 6.70 (dd, J = 15.7, 1.4 Hz, 1 H), 6.25 (dd, J = 15.7, 6.2 Hz, 1 H), 3.61–3.52 (m, 1 H), 1.46 (d, J = 7.0 Hz, 3 H). ¹³C NMR (101 MHz, CDCl₃): δ = 137.1, 131.6, 131.1, 129.5, 128.5, 128.2, 127.7, 127.3, 126.3, 123.7, 91.6, 82.7, 29.6, 21.7.
