  摘要：

  AbstractThe deoxygenation of 1‐alkyl‐3‐methyl‐3‐phospholene 1‐oxides, which may be regarded as trialkyl phosphine oxides (R3PO), and the reduction of dialkyl‐phenylphosphine oxides (R2PhPO) and methyl‐diphenylphosphine oxide (MePh2PO) have been elaborated by applying user‐friendly silanes, such as tetramethyldisiloxane (>SiH–O–HSi<) and polymethylhydrosiloxane ((O–SiH)n) under solvent‐free, catalyst‐free, and microwave (MW)‐assisted conditions. New silanes of type Ar2SiH2, alkyl2SiH2, and Ar3SiH were also applied in a few cases. The reactivity of the phosphine oxides and the silanes could be mapped on the basis of our experimental data.

  Platinum(II) complexes incorporating racemic and optically active 1-alkyl-3-phospholene P-ligands: Synthesis, stereostructure, NMR properties and catalytic activity

  摘要：

  Three 1-alkyl-3-phospholene 1-oxides, such as the P-ethyl, P-isobutyl and P-isopentyl derivative were prepared in racemic and enantiopure forms. After deoxygenation, the cyclic phosphines were converted to the corresponding phosphine-boranes and phosphine-platinum complexes (PtCl2L2, where L 1-alkyl-3-phospholene). The new products were characterized by spectral methods, and the stereostructure of the complexes was also evaluated by high level quantum chemical calculations. The platinum complexes were tested in the hydroformylation of the styrene. The extent of the regioselectivity towards branched aldehyde exceeds that measured with earlier platinum complexes. However, the enantioselectivity remained below 29%. (C) 2013 Elsevier B. V. All rights reserved.

  A fluorochemical composition for rendering a fibrous substrate oil and/or water repellent without substantially adversely affecting the look and/or feel of the fibrous substrate, comprising a fluorinated polyether compound and an extender. The fluorinated polyether compound comprises one or more perfluorinated polyether groups and the extender comprises a non-fluorinated organic compound comprising one or more blocked isocyanate groups and/or a carbodiimide compound.
