A recent emphasis in the chemistry of metal–metal bonds has been to prepare compounds with extremely short metal–metal distances and high metal–metal bond orders. But similar chemistry can be used to explore metal–metal bond orders less than one, including 2c/3e half-bonds. Bimetallic ...
X-Ray crystal structure determination of [AsPh4]+[NSF2NSO2F]– has revealed that the anion [NSF2NSO2F]– has three different types of S–N bonds with triple, double, and single bond character.DOI: 10.1039/C3978000226A 年份: 1978 收藏 引用 批量引用 报错 分享 全部来源 求助全文 RSC pu...
(b) reaction of a chiral molecule where bonds to the chiral center are not broken. * * CH3CH2CHClCH3 + Cl2, hv CH3CH2CHClCH2Cl + etc. A reaction that does not involve the breaking of a bond to a chiral center proceeds with retention of configuration about the chiral center. Ca...
The molecules of 2-benzoyl-1-benzofuran, C 15 H 10 O 2 , (I), interact through double C—HO hydrogen bonds, forming dimers that are further linked by C—HO, C—Hπ and π–π interactions, resulting in a three-dimensional supramolecular network. The dihedral angle between the benzoyl ...
hydroxylates mevastatin to form pravastatin and 6-epi-pravastatin.cCYP-sb21 catalyzes the oxidation of cyclosporine A (CsA) toγ-hydroxy-N-methyl-L-Leu4-CsA (CsA-4-OH) andγ-hydroxy-N-methyl-L-Leu9-CsA (CsA-9-OH). Functional groups and bonds colored in red are catalyzed by the P450...
