[(PNP)TiCl2] (PNP=N[2-PiPr2-4-methylphenyl]2) reacts with one equivalent of lithium derivative of diphosphane R2P-P(SiMe3)Li·nTHF (R=tBu, iPr) in toluene and forms the first complex with η1-coordination [(PNP)Ti(Cl){η1-P(SiMe3)-PtBu2}] (1) and complex with η2-coordination [(PNP)Ti(Cl){η2-P(SiMe3)-PiPr2}] (2) of phosphanylphosphido ligands to the titanium center. The similar reaction with two equivalents...
Structure of nitronorbornene derivative C14H12N2O2 synthesized in the reaction of cyclopentadiene with E-2-phenyl-1-cyano-1-nitroethene was determined by single crystal X-ray diffraction analysis. It was found that in analyzed molecule the nitro group is in endo-position whereas phenyl group have exo-orientation.
