Fe + SO3 = Fe(SO3) must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced...

The C atom linked to pyridine N converts PMS to SO5− and further to 1O2 by taking electrons from PMS. Both the free radical and non-free radical pathways contributed to the degradation of BPA. Despite being synthesized in different ways, these materials shared the common active structure ...
Synthesis of Magnetic SiC SiCp and SiCw (collectively referred to as SiC in the following description) were pre- modified with PSS aqueous solution respectively to make the SiC surface attach negative ions, so that the SiC surface had negative charge and was easy in absorbing and combining ...
其实早在上世纪60年代早就类似反应被发现,Pfitzner-Moffatt氧化反应(DCC/DMSO),Albright-Goldman氧化反应(Ac2O/DMSO),Parikh–Doering氧化(Py-SO3/DMSO),这些反应都用到DMSO作为活化试剂,但草酰氯的氧化体系副反应较少。最初用TFAA的方法活性非常高,但副反应也较多。反应后试剂产生的副产物...
