Reaktionen CH‐aktiver Verbindungen mit Aziden, XXX. Synthese von (Diazomethyl)phosphoniumsalzen durch Diazogruppen‐Übertragung

Abstract: Diazogruppen-Ubertragung auf die (Acylmethy1)triphenylphosphoniumsalze 10a -j rnit dem Azidiniumsalz 2 liefert die a-Diazophosphoniumsalze 12a -j neben dem 2-Aminobenzthiazoliumsalz 13; aus 15 entstehen die Diazoverbindungen 16 oder 17, je nach Molverhaltnis von 15 zu 2. -Durch Photolyse in Methanol wird 12a in die O/H-Insertionsverbindung 20 umgewandelt; die Zersetzung von 12j in Essigsaurelp-Toluolsulfonsaure flihrt zu 21. Die Umsetzung von 12b rnit 2 rnol Triphenylphosphan liefert das Bis(phosphonium)salz 2… Show more

“…The formation of benzenesulfonyl azide was accomplished according to the published procedure 16 . In brief, benzenesulfonyl chloride (10 g, 56.6 mmol, 1.0 eq) in acetone (100 mL) and sodium azide (5.52 g, 84.9 mmol, 1.5 eq) in water (20 mL) were combined yielding 9.6 g of the desired reagent as a colourless liquid (93%); 1 .0 eq) in dry THF (50 mL) was added dropwise to an ice-cold suspension of 60% sodium hydride (3.14 g, 78.6 mmol, 1.5 eq) in dry THF (50 mL).…”
