The reaction of 2,4,6-tris(trimethylsiloxy)-1,3,5-triazine with chlorocarbenium ions: a new access to 1-oxa-3-azabutatrienium and 2-azaallenium salts

Add time:07/13/2019    Source:sciencedirect.com

Chlorocarbenium salts 2a-d of the Vilsmeier-Arnold type react with the silylated isocyanuric acid 3 to give 1-oxa-3-azabutatrienium salts 1 under mild conditions. From reactions of diarylchloromethenium salts 2h-1 with 3 and ketones or tertiary carboxamides high yields of 2-azaallenium salts 9 were obtained. A few chloro substituted 2-azaallenium salts 5 were prepared from 1b and carbonyl compounds. The mechanisms of the new reactions are discussed.
