Ortho acid

Ortho acids are hypothetical organic compounds having the structure RC(OH)3 (R=alkyl or aryl).[1]

Ortho acids themselves are unstable and cannot be isolated. However orthoesters can be synthesized by the Pinner reaction, in which nitriles react with alcohols under acid catalysis:

RCN + 3 R′OH → RC(OR′)3 + NH3
