thankssss I must have erased that section in my book from my mind somehow...
A lot of it will depend on conditions, but basically cyanide is hydrolysed to amide (which is what I think you thought), but amide itself is usually hydrolysed faster to the acid. I'm not, however sure that LiAlD
4 reduction (or indeed the unlabelled version) is that efficient with acids, as typically these cause the lithium salt to crash out of solution in a kinetic sink.
