Hydrogen bund

In the course of this reaction, a molecule with activated car bon-hydrogen bunds, such as acetonitrile, is both metallaicd and carboxylated at the same time. A similar reaction, the insertion of CO into a mclallatcd phosphine ligand, was found in the thermolysis of U(dinpc) CI CO [53]. and the coordinated carbon dioxide carboxylates one methyl group of the dmpe ligand as shown in Equation (6).

Note the difference in the Fe—OI—D2 bond angles and the presumed hydrogen bund (dotted line) to the histidine (His E7). (From Shaanan. B. Nature (London) 1982,296, 683.

Cellulose consists of several thousand D-glucose units linked by l,4 -/3-glycoside bunds like those in cellobiose. Different cellulose molecules then interact to form a large aggregate structure held together by hydrogen bonds.
