Abstract
Addition of imine PhNC(Ar)R (Ar = Ph, R = Me;
p-MeOC6H4, R = H) to
(PhN)Mo(TMS-o-pda)(CH2
CMe2) 1
[TMS-o-pda = bis(trimethylsilyl)-o-phenylenediamide]
affords the corresponding η2-imine complexes
(PhN)Mo(TMS-o-pda)[PhN
C(Ar)R] 2a and 2b; analogous
reactions with aldimines RN
C(H)Ar (Ar =
p-MeOC6H4, R = CH2Ph, Et) afford
products (PhN)Mo(TMS-o-pda)[RNC(H)ArC(H)ArNR] 3a and 3b resulting
from reductive imine coupling, providing the first example of facile and
general Mo(IV) η2-imine complex formation.
