Hypothetical organic molecules of the form R–C(OH)3
In organic chemistry, ortho acids are organic, hypothetical chemical compounds having the structure R−C(OH)3 (R = alkyl or aryl).[1]
Ortho acids themselves are unstable and cannot be isolated. However, ortho esters can be synthesized by the Pinner reaction, in which nitriles react with alcohols under acid catalysis:
RCN + 3 R'OH → RC(OR')3 + NH3
