Preparation

edit

I always thought that orthoformates are prepared from hydrogen cyanide and alcohol in Pinner reaction. Treating chloroform with base in alcohol would result in carbene formation and whatever follows. Did not found that reaction in reaxys either. 89.76.50.226 (talk) 21:39, 3 October 2017 (UTC)Reply

Yes, chloroform reacts via carbenes with sodium methoxide. The substitution is via elimination/addition. So it is not really an exmaple of Williamson, mechanistically. You will find the reaction of CHCl3 with NaOEt in the database for sure. — Preceding unsigned comment added by 2001:4CA0:0:F295:BD9B:AE14:F4A4:A13E (talk) 20:58, 27 April 2022 (UTC)Reply
