Abstract:
Irradiation of 2-methylbenzoyl cyanide (3a) in acetonitrile solution results in the formation of its dimer, which upon loss of HCN gives rise to the cycloadduct 7a. The dimerization also proceeds efficiently with derivatives of 3a giving adducts 7b and 7c. When 2-methylaroyl cyanides are photolyzed in the presence of a more reactive acyl cyanide the mixed adducts 8a–e are obtained in excellent yields. The cycloadducts 7a–c and 8a–e react with carbon and nitrogen nucleophiles by a tandem addition–cyclization sequence furnishing substituted naphthols (10a and 10b) and isoquinolones (11a–d), resp

Abstract:
SummaryA new safe and sensitive method to determine hydrogen cyanide (HCN) in cigarette smoke using continuous flow analyser (CFA) has been developed and validated. The use of highly toxic potassium cyanide (KCN) as a standard necessitates the development of a safer method for the determination of HCN in cigarette smoke. In this described method KCN is replaced by less toxic potassium tetracyanozincate (Lethal Dose LD50 oral is 7.49 mg/kg for KCN and 2000 mg/kg for potassium tetracyanozincate). Furthermore, the new method uses isonicotinic acid-barbituric acid (coupling reagent) instead of pyr

Abstract:
Abstract The current AOAC procedure for semiautomated determination of niacin specifies the use of externally generated cyanogen bromide. Because of the safety concerns in handling this material, we investigated the use of an alternative system of generating cyanogen chloride in situ, using chloramine-T and potassium cyanide. Recovery studies conducted on 9 different food products yielded average recoveries of 101 %. A repeatability study resulted in a measured coefficient of variation of 2.9%. The AOAC niacin method was compared with this semiautomated method; 115 paired analyses on 8 differe

Abstract:
Light blue [Cu(CN)en2]I was prepared by reaction of copper iodide with ethylenediamine (en) and potassium cyanide in acetonitrile in air. It crystallizes in the space group C2 (No. 5) with a = 11.082(6), b = 7.155(2), c = 9.017(3) Å , β = 127.00(3)°, and Z = 2. The structure was refined from 1069 unique reflections and 90 parameters. The refinement converged to R1=0.018 and wR2=0.041 (all reflections). Copper has a trigonal bi-pyramidal environment formed by two en molecules and one CN− anion. The iodine anion shows no direct contact to the Cu2+ center. The propeller shaped complexes [Cu(CN)en
