- W2161092612 abstract "Complexes of formula TiCp(NPR 3 )(NMe 2 ) 2 (R = t-Bu 1, Ph 2) were prepared via salt metathesis of TiCp(NPR 3 )Cl 2 with a slight excess of LiNMe 2 . The species Ti(NP-t-Bu 3 )(NMe 2 ) 3 (3) was obtained as a by-product. The related derivative ZrCp(NP-t-Bu 3 )(NMe 2 ) 2 (4) was also prepared. Reaction of TiCp(NP-t-Bu 3 )Cl 2 with LiNHC 6 H 3 (2,6-i-Pr 2 ) afforded TiCp(NP-t-Bu 3 )(NHC 6 H 3 (2,6-i-Pr 2 ))Cl (5) and Ti(NP-t-Bu 3 )(NHC 6 H 3 (2,6-i-Pr 2 )) 3 (6). In a similar manner, the Zr analogs ZrCp(NP-t-Bu 3 )(NHC 6 H 3 (2,6-i-Pr 2 ))Me (7) and ZrCp(NP-t-Bu 3 )(NHC 6 H 3 (2,6-i-Pr 2 )) 2 (8) were also prepared. X-ray structural data for compounds 5, 6, and 8 are reported. Reactivity of these phosphinimideamide derivatives was explored. While these species do not yield imide derivatives upon thermolysis, reaction of 5 with excess AlMe 3 afforded TiCp(NP-t-Bu 3 )Me 2 while reaction with 1 equiv. of AlMe 3 gave TiCp(NP-t-Bu 3 )MeCl (9) and Al 2 (m-NHC 6 H 3 (2,6-i-Pr 2 )) 2 Me 4 (10). Key words: titanium, zirconium, phosphinimide, amide, ligand metathesis." @default.
