One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 3144-16-9, Name is ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonic acid, formurla is C10H16O4S.

(beta-Diketiminato)aluminum hydroxides and the chalcogenide derivatives: Precursors for homo- and heterometallic complexes with Al-E-M (E = chalcogen, M = metal) frameworks
The chemistry of organoaluminum hydroxides and related chalcogen derivatives is a topic of interest in view of their applications in material science and catalysis. The main interest of organoaluminum hydroxides is due to the tremendous importance of alumoxanes as catalysts or co-catalysts in the polymerization process, and these organoaluminum hydroxides are generally as the intermediates in the hydrolysis of alkyl aluminum compounds. The Bronsted acidic character of the Al-(OH) moiety determines the advantage in building up a new class of heterometallic compounds. Moreover, the heavier chalcogen derivatives with terminal EH (E = S, Se, or Te) groups generally require flexible and innovative synthetic strategies. Therefore, the successful synthesis of organoaluminum hydroxides, thiols, selenols, and tellurols results in kinds of interesting heterobimetallic compounds. The heterobimetallic molecules exhibit high activity in polymerization catalysis and supply more insight into the intramolecular architecture of heterogeneous catalysts. Herein, we summarize the development of organic ligand-supported aluminum hydroxides and the corresponding chalcogen derivatives especially stabilized by beta-diketiminate ligand in the past two decades, as well as their applications as building blocks for heterobimetallic compounds consisting of Al-E-M (E = chalcogen elements) skeletons.
