In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Tin-free radical cyclization reactions initiated by visible light photoredox catalysis, published in 2010-07-21, which mentions a compound: 676525-77-2, mainly applied to tin free radical cyclization visible light photoredox catalysis, HPLC of Formula: 676525-77-2.
Herein, we report an advancement in the application of visible light photoredox catalysts in a classic free radical mediated reaction, cyclization onto unactivated π-systems. The reactive radical intermediate is generated by the single electron reduction of an activated C-Br bond by an electron-rich redox catalyst afforded by a visible light induced catalytic cycle.
From this literature《Tin-free radical cyclization reactions initiated by visible light photoredox catalysis》,we know some information about this compound(676525-77-2)HPLC of Formula: 676525-77-2, but this is not all information, there are many literatures related to this compound(676525-77-2).
