Are "methyl isocyanide" and "carbylamine" the same thing?
The most recent IUPAC recommendations[1] states that:
P-61.9: Preferred IUPAC names are formed substitutively using the prefix ‘isocyano’ attached directly to a parent hydride.
This is a change from previous recommendations, and differs from some of your examples above.
To give a concrete example, $\ce{C6H5NC}$ should be named isocyanobenzene
- this is known as a PIN by IUPAC (preferred IUPAC name). Phenylisocyanide is also acknowledged as an acceptable trivial name (a name that does not conform to the recommendations but is still commonly used).
