Awful formatting.  At any rate,

    \scaleDurations #'(2 . 3) \clef treble

is not going to do a lot.  \scaleDurations only applies to the
immediately following music.  There are a few other oddities.
Personally, I'd rather scale the bass voice than the melody, but that's
probably a matter of taste.  Try


[Attachment #3 (text/x-lilypond)]

vl = \relative c''  \scaleDurations 2/3
{
  \time 6/8
  \set Staff.timeSignatureFraction = 6/8

  \clef treble 
  \key f \major
  \partial 8 c8
  a4 f8 c'4 f8
  e4. f4 c8 }

bs = \relative c {
  \time 2/4

  \key f \major
  \clef bass 
  \partial 8*2/3 s8*2/3
  f4 f, 
  c' a }

 \score {      
 <<
 \new Staff \vl
 \new Staff \bs
 >>


 \layout { 
   }
 }
