Reaction of (η5-C5H5)Re(NO)(PPh3)(CH 3) (2) with HBF4·O(C2H5)2 and HPF6·O(C2H5)2 (CH2Cl2, -78°C) gives reactive intermediates (1+BF4-, 1+PF6-) that are... JM Fernandez,JA Gladysz - 《Cheminform》 被引量: 148发表: 1989年 加载更多来源...
Answer to: Draw the Lewis structure and write the molecular geometry and hybridization on the central atom, and polar or nonpolar for SeO_2. By...
The cyclization would proceed through a carbocation intermediate 3a having sp2 flat structure (SN1 type mechanism) in CH2Cl2,in which the activation energies leading to both diastereoisomers are approximately identical, while in CH3CN alkylnitrilium salts 6a would be formed through the coordination of...
The unsaturated, "naked" cation [1H]BArF4 can be prepared by protonation of 1 with H(OEt2)2BArF4 in CH2Cl2 solution or by thermal elimination of MeCN from [1H(NCMe)]+. Crystallographic analysis confirms the structure of this 16e cation in [1H]BArF4. The formally unsaturated species 1 ...
Indeed, in CH2Cl2, 0.2 M NBu4PF6, or NBu4BF4, the electrolysis of the acid chloride in the presence of a catalytic amount of the cluster (1%) gives in good yields the acid fluoride RCOF, arising from the coupling of the acylium with a F- issued from the fluorinated supporting ...
Ru-4(CO)(8)(O2C6H4)(2).CH2Cl2 crystallizes in the noncentrosymmetric orthorhombic space group Pnn2 with a 13.9003(20) Angstrom, b = 8.6481(21) Angstrom, c = 10.6075(16) Angstrom, V = 1215.1(4) Angstrom(3), and Z = 2. The structure was refined to ...
