Alkylphosphinites as Synthons for Stabilized Carbocations
Ochmann, Lukas,Kessler, Mika L.,Schreiner, Peter R.
, p. 1460 - 1464 (2022/03/01)
We present a new acid-free method for the generation of carbocations based on a redox condensation reaction that enables SN1 reactions with a variety of nucleophiles. We utilize readily synthesized phosphinites that are activated by diisopropyl azodicarboxylate to form betaine structures that collapse upon adding a pronucleophile, thereby yielding reactive carbocation intermediates. We also employ this approach for the alkylation of some bioactive molecules.

A facile, direct and environmentally benign conversion of C(sp 3)-H bonds to C(sp3)-N bonds using substoichiometric amount of aprotic superelectrophiles polyhalomethane-AlX3 has been achieved by grinding under solvent-free
Adamantylazoles. Acid-catalyzed adamantylation of 1,2,4-triazoles

The reaction of 1-adamantanol with 1,2,4-triazole in sulfuric acid forms 1-adamantyl derivatives. In boiling chloroform containing traces of sulfuric acid, a mixture of isomeric N-adamantyl-1,2,4-triazoles is obtained. It is shown that 1-adamantyl carbocation is formed at a sulfuric acid concentration above 70%. 1997 Plenum Publishing Corporation.
