Usage

General Description

2-Butynyl acetate, also known as ethynyl ethanoate, is a chemical compound with the formula C6H8O2. It is a clear, colorless liquid with a fruity odor, commonly used as a flavoring agent in food products and as a component in perfumes and fragrances. 2-Butynyl acetate is also used in the synthesis of pharmaceuticals and as a solvent in chemical reactions. It is considered to be a potentially hazardous chemical and should be handled with care, as it can cause irritation to the skin, eyes, and respiratory system, and may have harmful effects if ingested or inhaled.

Practical Stannylation of Allyl Acetates Catalyzed by Nickel with Bu3SnOMe

A practical and scalable nickel-catalyzed allylic stannylation of allyl acetates with Bu3SnOMe is described. A variety of acyclic and cyclic allyl acetates, even with base-sensitive moieties, undergoes the stannylation by using NiBr2/4,4′-di-tert-butylbipyridine (dtbpy)/Mn catalyst system to afford highly functionalized allyl stannanes with excellent regioselectivity and yields. Furthermore, the scope of protocol is also extended by the reaction of propargyl acetates, giving rise to propargyl or allenyl stannanes. Additionally, a unique diastereoselectivity using the nickel catalyst different from the palladium was demonstrated for the stannylation of cyclic allyl acetates. In the reaction, inexpensive and stable nickel complexes, abundant reductant (Mn), and atom-economical stannyl source were used.

HIGHLY STEREOSELECTIVE SYNTHESES OF CONJUGATED E,E- AND E,Z-DIENES, E-ENYNES AND E-1,2,3-BUTATRIENES VIA ALKENYLBORANE DERIVATIVES

A highly selective and potentially general methodology for the synthesis of conjugated E,E- and E,Z-dienes, E-enynes, and E-1,2,3-butatrienes via hydroboration of alkynes is reported.The observed stereoselectivity was >98-99percent.
