Phase-Transfer Synthesis of Arenediazocyanides and Synthesis of Arenediazosulfones from Arenediazonium Cations and the Formation of Reduced Pyridazines by 2 + 4 Cycloaddition Reactions

Article abstract of DOI:10.1021/ja00366a030

The remarkably versatile arenediazonium cations are also convenient to use and nondangerous when utilized as the BF4 or PF6 salts.Arenediazonium compounds have recently been shown to undergo the 2 + 4 Diels-Alder cycloaddition, but the reaction is solvent
