Abstract
Auf die ungewöhnlich starke Lewis‐Basizität des P‐Atoms und auf die Fähigkeit zu unterschiedlich starken transanularen P‐N‐Wechselwirkungen ist die hohe katalytische Aktivität von [P(MeNCH2CH2) 3N] in der Titelreaktion zurückzuführen. So bildet sich, wie rechts angedeutet, in 3 min Triphenylisocyanurat (Ar = C6H5) in 97% Ausbeute und in 8 min Tri‐para‐methoxyphenylisocyanurat (Ar = 4‐MeOC6H4) in 99% Ausbeute. magnified imageKeywords
