Aminoderivate von α‐P4S3, α‐P4Se3 und P3Se4 – Daten und Analyse der 31P‐NMR‐Spektren in Lösungen

Amino Derivatives of α‐P₄S₃, α‐P₄Se₃, and P₃Se₄; Data and Analyses of their ³¹P NMR Spectra in Solution α‐P₄S₃I₂, α‐P₄Se₃I₂, and P₃Se₄I were reacted with primary and secondary amines in CS₂. The reaction yields exo‐exo isomeres of α‐P₄S₃L₂ and α‐P₄Se₃L₂, the N‐bridged compounds α‐P₄S₃L′ and P₃Se₄L, with L = NHR¹, NPhR², THC (R¹ = ^tBu, Ad, Ph, Flu, TPMP; R² = Me, Et, ⁱPr), and L′ = NR¹. The ³¹P NMR data of the compounds in CS₂ solution were measured. By the reaction of α‐P₄Se₃I₂ with primary amines NH₂^tBu and NH₂Ad in CS₂ an asymmetric isomer α‐P₄Se₃I_endo(NHR¹)_exo was observed for the first time in the ³¹P NMR spectra. The influence of the ligands L on the ³¹P NMR parameter of α‐P₄S₃L₂, α‐P₄Se₃L₂, and P₃Se₄L is discussed.
