reactive. It has a boiling point of 85.0°C. The autoignition
temperature for 3-butyn-2-one is 274°C. 3-Butyn-2-one has a penetrating odor and is a lacrimator. 3-Butyn-2-one has a penetrating odor and is a lacrimator.
3-Butyn-2-one was used in the synthesis of clerodane diterpenoid (+/-)-sacacarin. It was used as substrate in stereoselective, conjugate arylation mediated by gallium(III) chloride leading to (E)-α,β-unsaturated ketones.
ChEBI: Butyn-2-one is a methyl ketone and a terminal acetylenic compound. It is functionally related to a butan-2-one.
3-Butyn-2-one undergoes asymmetric double-Michael reaction with ortho-tosylamidophenyl malonate catalyzed by chiral aminophosphines to yield indolines. It undergoes double Michael reaction with nitrogen-containing tethered diacid to give pipecolic acid derivatives.
