Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 5570-77-4, Name is 4-Chloro-1-methylpiperidine, molecular formula is , belongs to piperidines compound.

FeCl3-Mediated Carbenium Ion-Induced Intramolecular Cyclization of N-Tethered Alkyne-Benzyl Alkanols
An intramolecular carbenium ion induced cyclization of N-tethered alkyne-benzyl alkanols mediated by ferric chloride (FeCl3) leading to substituted pyrrolidines and piperidines with exocyclic chloro-alkylidene and -arylidene moiety in good yields has been described. The reaction proceeds in an anti-fashion in both the cases. Ferric chloride acts both as Lewis acid as well as chloride nucleophile.
