Description

General description

The formation mechanism and oxidation route of 3-buten-2-one was studied.

Application

3-Buten-2-one was used in the synthesis of 4-methoxy-butan-2-one by the conjugate addition of methanol. It was also used as a substrate in an iron(II)-catalyzed alkylation of indoles at the C-3 position. 3-Buten-2-one was also useful in Micheal acceptor reactions for thiols, indoles and coumarins.

Packaging

5, 100, 500 mL in glass bottle
