| | 3-Butyn-2-one Usage And Synthesis |
| Chemical Properties | clear yellow to orange-brown liquid | | Chemical Properties | 3-Butyn-2-one is a clear, colorless liquid that is chemically
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. | | Uses | 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. | | Definition | ChEBI: Butyn-2-one is a methyl ketone and a terminal acetylenic compound. It is functionally related to a butan-2-one. | | General Description | 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. |
