The reaction between CH30H or CIHSOH and 1, I-dimethylsilaethene, the disproportionation product of the trimethylsilyl radical, has been studied to establish its efficiency for quantitative measurement of the disproportionation reaction. It has been found that standing in a Pyrex vessel, in mixtures
The effect of Tl substitution for Hg in the Hg-Ba-Cu-O system has been investigated for a wide substitution range. A single-layer system was maintained until 50% of Tl substitution, and above 50%, a double-layer system was observed. Tl substitution brought about an overdoping state in the CuO 2 plan
C(4), CΠ(2)-Double substitution was achieved in good yields by reacting 3-arylsydnones with BuLi and then with a suitable electrophile in THF at β«05Χβ¬ΠC. α§ 1998 John Wiley & Sons, Inc.
