Introducing the reaction results using a flow-type microwave synthesis device in detail!
Our "flow-type microwave synthesis device" can heat the entire system while flowing the target substance (liquid) through a glass serpentine tube, eliminating the need for multiple heating steps and enabling uniform heating. Using this device, we will introduce the reaction results and experimental methods for the synthesis of 2-allylphenol via a Claisen rearrangement reaction using allyl phenyl ether as the starting material. 【Overview】 ■ Under the conditions of microwave output 100W and flow rate 0.5 mL/min, using N,N-dimethylformamide (DMF) as the reaction solvent (applied pressure ca. 1.7 MPa, ca. 290℃), the progress of the reaction was confirmed by TLC analysis, and the chemical structure of the product was determined by NMR analysis. ■ As a result, the disappearance of the starting material was confirmed, and the desired 2-allylphenol was obtained as the main product. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Sida FDS Co., Ltd. was established as the development division of the Sida Group, which consistently engages in "monozukuri" (manufacturing) to meet customer needs, from machining parts for machine tools and industrial machinery to the assembly of complete systems. Our goal is to develop and sell products that can be patented, not only in Japan but also globally. Moving forward, we aim to be a manufacturer that is needed by society through the development of our own products (such as environmental evaluation testing equipment and microwave irradiation devices for chemical applications).
