Synthesis and characterization of a masked N-heterocyclic phosphinidene (NHP)

Universität Rostock, 2021

Abstract: This thesis summarizes the synthesis and characterization of an unprecedented heterocyclobutane derivative. To assess the biradical character, quantum mechanical computations were carried out. The second part elaborates on the reactivity (LEWIS acids/bases, an isonitrile, carbon monoxide, chalcogens). Notably, the addition of alkenes/alkynes to form phosphiranes/phosphirenes highlights the phosphinidene-type reactivity. In the last part, heavier congeners (As, Sb, Bi) of chlorinated precursors and theoretical investigations of their corresponding reduced heterocycles is discussed.
