Unprecedented Zinc–Borane Complexes

{CH2(PPh2=NSiMe3)(PPh2=S)} and {CH(PPh2=NSiMe3)(Ph2P=S)}– as Ligands in Zinc Chemistry: Synthesis and Structures

“…In the solid state, the zinc atom is coordinated by the phosphinimine nitrogen and sulfur atoms [Zn-N1 2.016(3), Zn-S 2.4612 (11) . [41] By considering the Zn-C13 distance as a bond, the coordination polyhedron of the Zn atom can be considered as a distorted tetrahedron. A six-membered metallacycle (N-P1-C13-P2-S-Zn) is formed by the {(PPh 2 =NSiMe 3 )(PPh 2 =S)CH} -ligand and the zinc atom.…”

“…Addition of the heterocumulenes di-(p-tolyl)carbodiimine and diphenylketene to [{(Me 3 SiNPPh 2 ) 2 [41] Recently, our attention has been attracted by the (iminophosphoranyl)(thiophosphoranyl)methanide ligand {CH(PPh 2 =NR)(Ph 2 P=S)} -, which is isoelectronic with the bis(phosphinimino)methanide ligand. The synthesis of {CH 2 (PPh 2 =NSiMe 3 )(PPh 2 =S)} by the reaction of {Ph 2 PCH 2 (PPh 2 =NSiMe 3 )} with sulfur in toluene at reflux was reported by So and co-workers.…”

“…[8][9][10][11][12][13][14][15][16][17][18] We have also reported on bis(phosphinimino)-methanide zinc complexes. [40,41] Bis(phosphinimino)methane {CH 2 3 )(PPh 2 =S)CH}ZnPh], respectively. In addition to the coordination of the phosphinimine nitrogen and sulfur atoms to the zinc atom, a long contact between the methine carbon atom of the P-C-P bridge and the zinc atom was observed in these complexes.…”

(Iminophosphoranyl)(thiophosphoranyl)methane rare-earth borohydride complexes: synthesis, structures and polymerization catalysis

“…Both ligands have been extensively used in main group, 1-16 transition [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] and f-element 5,13,15,19,[35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] chemistry. Both ligands have been extensively used in main group, 1-16 transition [16][17][18][19][20][21][22][23][24][25][26][27][28][29]…”

Syntheses and Structures of Zinc Bis(phosphinimino)methanide Complexes

“…Zinc complexes containing neutral (type I ),5 monoanionic (type II ),5,6 and dianionic ligands (type III ),7 respectively, have been synthesized and structurally characterized and their promising activity in ring‐opening polymerization (ROP) of rac ‐lactide was proven by several research groups 8. These experimental studies also demonstrated that bis(phosphinimino)methanide ligands in such complexes should be rather regarded as non‐innocent ligand since they were found to easily react with heterocumulenes with activation of the backbone CH and subsequent formation of tridentate complexes 6a,6c…”
