Readily Available Onio-Substituted Methyleneiminium Salts: Single Precursors for a Variety of Aminocarbenes

5 páginas, 1 figura, 3 esquemas.From amides to carbenes: Phosphonio-substituted iminium salts are readily available from the corresponding amides in a one-pot reaction. Deprotonation followed by substitution reactions affords a variety of transient and stable amino carbenes.We are grateful to the ACS/PRF (38192-AC4) and RHODIA for financial support of this work, and to the Spanish Ministerio de Educacion, Cultura y Deporte for a postdoctoral fellowship (S C).Peer reviewe
