functional groupschemical spacesulfoximinesTwo synthetic routes to sulfondiimidamides have recently been reported.The ability to prepare andmanipulate sulfondiimidamides,which are the double aza-analogs of sulfonamides,in an efficient and predictable way,opens new possibilities for exploring chemical space....
Disodium 1, 6-disulfido-1, 3, 5-cycloheptatriene 3, formed by reduction of 1 with sodium in liq. ammonia, reacts with hydrogen chloride and methyl iodide to give 1, 6-dimercapto-, 4, and 1, 6-bis(methylthio)-1, 3, 5-cycloheptatrienes 5 respectively; however, it is oxidized by ...
When high reduction potential is applied, e.g., severe reduction conditions are used, it is possible to reduce all the sulfur groups. If the severity of the reduction conditions in a cell that contains a mixture of sulfur groups is gradually increased, the easily reduceable groups will ...
These are some of the major functional groups, although many others do exists, including additional nitrogen groups and sulfur groups and derivatives of these functional groups. Alcohols Alcohols are a common functional group.Alcoholscontain a carbon bound to an OH group.Naming alcoholsend with the ...
Lithium–sulfur (Li–S) batteries are expected to overcome the limit of current energy storage devices by delivering high specific energy with low material cost. However, the potential of Li–S batteries has not yet been realized because of several techn
functionalized 1,3-butadienesA variety of novel 1,3-butadienes with one or two sulfur-containing groups are easily accessible by sigmatropic rearrangement reactions. Furthermore, a new sequence of sigmatropic migrations leads to 1,2-difunctionalized 1,3-butadienes.doi:10.1080/10426509908546453...

In this study, a systematic first-principles density functional theory calculation is adopted to understand the interactions between graphene and graphene with oxygen containing functional groups (hydroxyl, epoxy and carboxyl groups) and sulphur (S8) and long chain lithium polysulfides (Li2S8 and Li...
Sampling site CS exhibited diverse genes involved in the methane, sulfur, and nitrogen cycles (Fig.2b), suggesting that CS harbored a wide range of functional groups with great metabolic potential. Notably, there were few significant differences in the abundances of representative functional genes am...
During the etching of A layers from MAX phases, the surface of Mn+1Xn is covered with functional groups such as oxygen (O), fluorine (-F), or hydroxyl (-OH) that leads to the formation of Mn+1XnTx, where Tx represents the surface terminating functional groups. The unique combination ...
