Asymmetric synthesis of alpha,alpha-dibranched propargylamines by acetylide additions to N-tert-butanesulfinyl ketimines.

Andrew W Patterson et al.

The Journal of organic chemistry, 71(18), 7110-7112 (2006-08-26)

Addition of lithium acetylides prepared from 1-pentyne, phenylacetylene, and trimethylsilylacetylene to diverse N-tert-butanesulfinyl ketimines affords a range of alpha,alpha-dibranched propargyl sulfinamides in generally good yields (up to 87%) and with high diastereoselectivities (up to >99:1). Acidic cleavage of the tert-butanesulfinyl

Chromene chromium carbene complexes in the syntheses of naphthopyran and naphthopyrandione units present in photochromic materials and biologically active natural products.

Manish Rawat et al.

Journal of the American Chemical Society, 128(34), 11044-11053 (2006-08-24)

The carbene complex 5-(2,2-dimethyl-2H-chromene)methoxylmethylene chromium pentacarbonyl will undergo a benzannulation reaction with phenylacetylene, 1-pentyne, 3-hexyne, and trimethylsilylacetylene to give 7-hydroxy-10-methoxy-3H-naphtho[2.1-b]pyrans as the primary product. These compounds are difficult to obtain pure due to their sensitivity to air. If the benzannulation

The irreversible formation of palladium carbide during hydrogenation of 1-pentyne over silica-supported palladium nanoparticles: in situ Pd K and L3 edge XAS.

Min Wei Tew et al.

Physical chemistry chemical physics : PCCP, 14(16), 5761-5768 (2012-03-17)

The catalytically active phase of silica-supported palladium catalysts in the selective and non-selective hydrogenation of 1-pentyne was determined using in situ X-ray absorption spectroscopy at the Pd K and L(3) edges. Upon exposure to alkyne, a palladium carbide-like phase rapidly
