To list:

Greetings! The pKa of acetonitrile is known to be 24; deprotonation occurs
easily with strong bases or alkali metals. The pKa of Cyanoform was
measured back in the 50's at Dupont, to be -5 (yes, minus 5!) in either
H2SO4 or HClO4. A pKa value of 11.2 appears to be too high for
malononitrile; it could be around 4-6.
