Possible reaction of a ketal with a Grignard reagent?
Do ketals react with gringard reagents? A better question is 'Do they react with gringards more quickly than nitriles react with gringards?'
Couldn't find anything with google.

Acetals do not react with grignards. You can not have a nucleophilic addition on a multiple bond where there is no multiple bond, such as in acetals.
Furthermore, acetals can be used as solvents for the formation of grignard reagents and for their reactions (for example, methylal is a good solvent
for grignard reactions, see N. P. Cheremisinoff: Industrial Solvents Handbook, or similar reviews).

Perhaps because you were searching for "ketals" which is a rarely used term. "This term, once abandoned, has been reinstated as a subclass of acetals." More likely though, you did not invest enough effort (I found the
answer using Google in 5 seconds).
PS: Open threads without references only in the Beginnings section. See the forum guidelines for more information.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)
