Reactions of POP-pincer rhodium(I)-aryl complexes with small molecules: coordination flexibility of the ether diphosphine

Electrochemical reactions of pincer rhodium(I) complexes

The electrochemical properties of the (PCP)Rh(H2) (1-H2, PCP 1⁄4 k-C6H3e2,6-(CH2P(Bu2)) complex was examined by cyclic voltammetry in acetonitrile (MeCN), dimethylsulfoxide (DMSO) and 1,2difluorobenzene (1,2-DFB). Upon oxidation in weakly or non-coordinating media such as 0.05 M NaBAr24 in 1,2-difluorobenzene, simple one electron oxidation to [(PCP)RhII(H2)]þ is observed. Conversely, in coordin...

Lead(II) nitrate and hexafluorosilicate complexes with neutral diphosphine coordination.

Rare examples of phosphine complexes of lead(II) are reported. The reaction of Pb(NO3)2 with Me2P(CH2)2PMe2, o-C6H4(PMe2)2 or Et2P(CH2)2PEt2 (L-L) in H2O/MeCN gave white [Pb(L-L)(NO3)2], irrespective of the ratio of reagents used. The X-ray structures of [Pb{Me2P(CH2)2PMe2}(NO3)2] and [Pb{o-C6H4(PMe2)2}(NO3)2] reveal chelating diphosphines and κ(2)-NO3(-) groups occupying one hemisphere about t...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
