Hashmi, A. S. K.Science of Synthesis, (200725346.

Various Grignard reagents 25 can be successfully converted into aldehydes 26 by treatment with triethyl orthoformate followed by an acidic workup (Scheme 12).[‌55‌,‌56‌] Closely related acyclic[‌57‌,‌58‌] and cyclic ortho esters[‌59‌,‌60‌] can also be used.
