  The phospha-Wittig reactivity ofβ-diketiminate titanium(III) complexes with phosphanylphosphido ligands was investigated. The reactions of [MeNacNacTi(Cl){η2-P(SiMe3)-PtBu2}] and [MeNacNacTi(Cl){η2-P(SiMe3)-P(Ph)tBu}] with acetone conducted in toluene solution under mild conditions led to the phospha-Wittig intermediates [{(ArN=C(Me)CHC(Me)=NAr)(C(Me)2O}Ti(Cl){PtBu2-P(SiMe3)C(Me)2O}] (1) and [{(ArN=C(Me)CHC(Me)=NAr) (C-(Me)2O}Ti(Cl){P(Ph)tBu-P(SiMe3)C(Me)2O}]...

  All our former experience with application of quantum theory seems to say that what is predicted by quantum formalism must occur in the laboratory. But the essence of quantum formalism-entanglement, recognized by Einstein, Podolsky, Rosen, and Schrödinger-waited over 70 years to enter laboratories as a new resource as real as energy. This holistic property of compound quantum systems, which involves nonclassical correlations between...

  While entanglement and violation of Bell inequalities were initially thought to be equivalent quantum phenomena, we now have different examples of entangled states whose correlations can be described by local hidden-variable models and, therefore, do not violate any of the Bell inequalities. We provide an up-to-date overview of the existing literature regarding local hidden-variable models for entangled quantum states, in both...
