DESCRIPTION:Non-Classical Double Bonds – Phoshaalkenes and Phosphaalumen
 es\nHeavier element–element multiple bonds had been long considered inac
 cessible but have now moved beyond the status of lab curiosities. However\
 , heteroatomic E13═E15 (E13 = Al\, Ga\; E15 = N\, P\, As) multiple bonds
  are still scarcely represented. Due to alternating Lewis acidic and Lewis
  basic centers\, E13=E15 species are prone to oligomerize. Oligomerization
  can be suppressed by either kinetic\, acceptor or donor stabilization. In
  our quest to design novel phosphaalkene-based ligand systems through the 
 so-called phospha-Wittig reaction\, we have uncovered the potential of pho
 spha-Wittig reagents (ArPPMe3) as phosphinidene transfer reagents. These s
 pecies allow facile access to phosphaalumenes and -gallenes in the reactio
 n with sources of Al(I) opr Ga(I)\, respectively.
