一般描述

Chloroacetaldehyde dimethyl acetal is a clear, colorless liquid. It reacts with hydroxythiol to form hydroxy acetal[1].

应用

Chloroacetaldehyde dimethyl acetal can be used as a reactant to synthesize:
  • 2-(chloromethyl)-4,7-dethyl-1,3-dioxepane[2]
  • 2-(chloromethyl)-5,6-benzo-1,3-dioxepane[2]
  • ketene dimethyl acetal[3]

Chloroacetaldehyde dimethyl acetal was used to investigate the enzymes used for activation and transformation of vinyl chloride[4]. It was also used for introducing O-(2,2-dimethoxyethyl) groups into amylose, dextran, and a linear (1→3)-β-D-glucan[5]. Chloroacetaldehyde dimethyl acetal was utilised in the synthesis of ethoxyacetylide[6].
