Paragraph 0060; 0061; 0063; 0065; 0067, (2018/04/28)
The invention provides a cyclopentadecanone preparation method. The method includes that cyclododecene and acryloyl chloride are subjected to reaction to obtain a ketene intermediate shown as a formula (II), the intermediate and a sulfuryl hydrazine compound are subjected to reaction to obtain a hydrazone intermediate shown as a formula (III), and the hydrazone intermediate is subjected to ring opening and hydrogenation to obtain a cyclopentadecanone product shown as a formula (V). Compared with a traditional cyclopentadecanone synthesis route, the method mainly has advantages of low cost andeasiness in acquisition of starting materials, the ketene intermediate shown as the formula (II) is obtained by high-selectivity reaction of cyclododecene and acryloyl chloride, and the integral synthesis route is simple and short in step, high in total yield and applicable to cyclopentadecanone industrial production.
