Abstract
Comparative investigations of the mass spectra of eEH2, Me2EH, Et2EH(E = N, P); Me3E, Et3E(E = N, P, As, Sb, Bi). (n‐Pr)3E(E = Sb, Bi); (n‐Bu)3E(E = P, As); (n‐C5H11)3As and (n‐C6H13)3As as well as Et2AsBr have been carried out. Deuteroanalogues, metastable transitions and low voltage spectra were used for elucidation of the fragmentation paths. The mass spectra of MeN(CH2)2 and CD3N(CH2)2 were studied to analyse the structure of the fragments. The main degradation path of amines, i.e. α‐cleavage, was shown to be untypical for P, As, Sb and Bi derivatives.
