Neuere Methoden der präparativen organischen Chemie IV. Isonitril-Synthesen

Abstract

drei Werten fur Reflexintensitat und Untergrund rechts und links vom Reflex werden zusatzlich die Reflexintensitaten rechts und links vom eingestellten Glanzwinkel gemessen (vgl. Abb. 9) und ausgegeben. Aus dem Verhaltnis dieser beiden Werte errnittelt die Rechenmaschine eine etwaige Verschiebung der Reflexkurve. Diese Art der Messung benotigt keine zusatzliche MeBzeit, da die drei Reflexmessungen fur die Auswertung zusammengezahlt werden konnen; die Summe bestimmt den statistischen Fehler der Gesamtmessung.

Synthesis of polyampholyte microgels from colloidal salts of pectinic acid and their application as pH-responsive emulsifiers

“…The critical concentration of chain entanglement, C*, is approximately 0.5 wt.% [16]. 1,4-Bis(3-isocyanopropyl)piperazine was synthesized according to the well-known protocol [24]. Benzylamine, 4-fluorobenzylamine, and furfurylamine were purchased from Acros Organics (Germany).…”

Structural Investigation of Bis(isonitrile)gold(I) Complexes

Starting materials were either commercially available or were pre pared following literature procedures: MeNC[7], PhNC[8], MesNC[9] (Mes = mesityl), (MeNC)AuCl[10,11], (PhNC)AuCl and (MesNC)AuCl[6 , 12],Bis(methylisonitrile)gold(I) triflate, (I)To a solution of (MeNC)AuCl (100 mg, 0.367 mmol) in 60 ml of dichloromethane a solution of MeNC (15 mg, 0.367 mmol) and AgCF^SCb (94 mg. 0.367 mmol) in 10 Brought to you by | New York University Bobst Library Technical Services Authenticated Download Date | 7/1/15 11:36 AM…”

Asymmetric Synthesis of α-Methylornithine

“…6a; IR J)! !~ cm- a-.M.ethylornithine (7) A solution of 6 (7 g, 19 mmol) in 50 ml of 5 Nhydrochloric acid was heated at 80", 90°C for 24 hr. After removal of menthol by ether extraction, the aqueous phase was adjusted to pH 2 with sodium hydrogen carbonate and applied to a Dowex 50 X 8 column (H+ form).…”
