Carbenes Part 2: Cyclopropanation, C-H Insertion, and the Bamford-Stevens Reaction

The video tutorial explores the fascinating world of carbenes, electron-deficient carbon species with two nonbonding electrons. It covers their general formula, properties, and applications, such as cyclopropanation and insertion into sigma bonds. The tutorial distinguishes between singlet and triplet carbenes, highlighting their different reaction mechanisms and stereochemical outcomes. It also introduces the Bamford Stevens reaction, which converts ketones into alkenes using carbene chemistry. Throughout, the video emphasizes the importance of stereochemistry and the potential for various synthetic applications.
