C-E-G to C#-E#-G# as late Romantic voice leading

It works perfectly in the tonalities of E or B in highly chromatic but
tonal writing.

For example

E major -> C major -> C# major -> F# minor -> B major -> E major

or

B minor -> C major -> C# major -> F#7 -> B

something I would not at all be surprised to find Reger or Strauss
doing. Or as part of more complicated harmony:

B-D-F#-B to C-E-G-B to C#-E#-G#-B to C#-E-G-B to C#-E-F#-A# and back
to B again.

As for Reger, he is an unacknowledged master of harmony, which very
much includes voice-leading: see the unaccompanied choral works.
