3-Prop-2-ynoxypropane-1,2-diol

3-Prop-2-ynoxypropane-1,2-diol is an electroplating intermediate that can be used to formulate electroplating brighteners, and is used in combination with alkynyl alcohol derivatives to synergise light production and enhance ionic co-deposition.

3-Prop-2-ynoxypropane-1,2-diol is prepared by the reaction of propargyl bromide and (R,S)-2,2-dimethyl-1,3-dioxolane-4-methanol. The specific synthesis steps are as follows:
Step 1: propargyl bromide; (R,S)-2,2-dimethyl-1,3-dioxolane-4-methanol With sodium hydride In tetrahydrofuran Reflux;
Step 2: With hydrogenchloride In tetrahydrofuran; methanol; water at 20℃; for 8h.
