1,2,4-Azadiphosphole

1,2,4-Azadiphosphole. Ionkin, A. S.; Ignat'eva, S. N.; Litvinov, I. 1609-86-5 and 139079-70-2 are also occured in this study. A.; Naumov, V. A.; Arbuzov, B. A. (A. E. Arbuzov Inst. Org. Phys. Chem., Kazan 420083, USSR). Heteroat. Chem., 2(5), 577-81 (English) 1991. CODEN: HETCE8. ISSN: 1042-7163. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 28, 75 PYCNHCMe3 dimerizes in alk. medium to azadiphosphole I, the first representative of 1,2,4-azadiphospholes. The structure of I has been detd. by IR and 31P NMR spectroscopy and by x-ray crystallog. .

Diazanickelacyclopentanones from nickel(0), imines and isocyanates

Diazanickelacyclopentanones from nickel(0), imines and isocyanates. Hoberg, Heinz; Suemmermann, Klaus (Max-Planck-Inst. Kohlenforsch., Muelheim D-4330, Fed. Rep. Ger.). J. Organomet. Chem., 253(3), 383-9 (German) 1983. CODEN: JORCAI. ISSN: 0022-328X. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) RNCO (R = Me, Bu, CMe3, Ph, 4-tolyl, cyclohexyl) coupled oxidatively with PhCH:NPh at Ni(0) in the presence of L (L = Me2NCH2CH2NMe2), 2,2'-bipyridine) to form diazanickelacyclopentanones I. The structure of I was detd. by spectroscopic and chem. methods. 1609-86-5 and 103-71-9 are just another two chemicals used in this study. Hydrolysis of I (L = Me2NCH2CH2NMe2) gave 53-90% PhCH2NPhCONHR. .
