As the pi-bond leaves the first carbon, it becomes positively charged due to lose of electron, and the H gets converted to H X − (hydride ion) as it accepts electron. Therefore, it is called hydride shift. WebName: ANSWERS Student ID: Student Signature: CHEM*4730 SYNTHETIC ORGANIC CHEMISTRY Fall Semester, 2024 Department of. Expert Help. Study ...

"WebAnd you might want to do this, because mesylates and tosylates are better leaving groups. So if we look at a general reaction to form a tosylate, you would start with an alcohol and you'd add tosyl chlorides and also pyridine, and you would form your tosylate over here on the right. When we look at the mechanism, we start with tosyl chloride. " - Tsoh and heat organic chem

p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. The CH3C6H4SO2 group is known as the tosyl group and is often abbreviated as Ts or Tos.
