A new method for the synthesis of terminal and internal alkynes from the nickel‐catalyzed decarboxylative coupling of N‐hydroxyphthalimide esters and bromoalkynes is presented. This reductivecross‐electrophilecoupling is the first to use a C(sp)−X electrophile, and appears to proceed via an alkynylnickel intermediate. The internal alkyne products are obtained in yields of 41–95 % without the need

this position favored binding of linoleate with the carboxylate group near the surface of the enzyme (tail-first binding), resulting in formation of 13(S)-HPOD. They also proposed that smaller residues in this position facilitate binding of linoleate in a head-first manner with its carboxylate group interacting with a conserved arginine residue (arg-707 in SBLO-1), which leads to 9(S)-HPOD. In the present

A method is provided for preventing copper and zinc from being eluted from a copper-alloy-made plumbing instrument that includes valves and pipe joints and suppresses copper and zinc from being eluted from the copper-alloy-made plumbing instrument while using for the plumbing instrument copper alloy as-is that includes bronze and brass, to provide a copper-alloy-made plumbing instrument using the method and to provide a film-forming agent. The method forms on at least a liquid-contact portion of the copper-alloy-made plumbing instrument a film of an organic substance comprising unsaturated fatty acid and coating with the film both copper and zinc in the surface layer of the liquid-contact portion of the plumbing instrument, thereby suppressing the elution of copper and zinc.
