“…Die vorliegenden Ergebnisse verdeutlichen somit, dass nicht nur die elektronischen Strukturen der Phosphaalkine (mit oder ohne π‐Donorsubstituenten),13 sondern auch die der N‐heterocyclischen Carbene den Reaktionsweg bei der Adduktbildung bestimmen. Generell lässt sich die Bildung dreier verschiedenen Phosphaheterocyclen (Typ 4, 5 oder 7 ) erwarten.…”

“…published the structure of a zwitterionic species, [{( i Pr) 2 NC} 2 P 2 Se 2 ], which has a non-coordinated R 2 PSe 2 À unit. 7 It should be noted that the structure of free diselenophosphonate [(R)(OR)PSe 2 ] À or its salts is still unknown. 8 On the other hand, the involvement of the ammonium salt of any dsep ligand as the source of ammonia in the formation of 4-oxopiperidinium rings is still unknown.…”

“…The results presented here demonstrate clearly that both the electronic structures of the phosphaalkyne (with or without π‐donor substituents),13 as well as those of the N‐heterocyclic carbenes determine the reaction pathway of the adduct formation. In general the formation of three different types of phosphaheterocycles (type 4, 5 , or 7 ) may be expected.…”
