“…[44,47,48] The thermal stability of 19 (mp 423-424 K) allowed us to conduct its X-ray analysis at an elevated temperature (413 K), and a greater C1-C2 bond length was observed [1.791(3) Å], which represents the longest C-C bond ever reported among uncharged molecules. [51,52] One of the intriguing reactivities of 17 and DSAP 19 is the oxidative protonolysis of the highly expanded C1-C2 bond. Treatment of 17 with a Brønsted acid such as TsOH caused its transformation into bis(10-methylacridinium) 18 2+ accompanied by C1-C2 bond cleavage.…”

“…I n der Gruppe der Pentaphosphane (7) Offenbar stehen die sterischen Verhaltnisse von 5 der Substitutionsreaktion im Wege, so daB die Umlithiierung den Reaktionsablauf bestimmt. Aus der Zwischenstufe a bildet sich unter Abspaltung von Me,SiCl Verbindung 6 voraussichtlich uber das Phosphen analog der Bildung von P,[P(CMe,),],[CMe,], [4]. Das ,lP-NMR-Spektrum von 12 zeigt funf chirale P-Atome, wodurch 16 Disstereomere ermoglicht werden.…”

“…The nortricyclic P 7 core arrangement found in 2 has been observed in a number of anionic and neutral P x nÀ cage structures. [9] However, the Cr 0 complex [{P 7 (PtBu 2 ) 3 }{Cr(CO) 4 } 2 ], [14] which contains a neutral, nortricyclic P 7 (PtBu 2 ) 3 ligand, is the closest analogue to 2.…”
