On reaction with N,N-dichloro-t-butylamine or -cyclohexylamine in benzene at 0 "C, nickel tetracarbonyl evolves three moles of carbon monoxide per mole. A colorless precipitate ( I ) is formed that has a Ni:N ratio of 1 : 1 and is insoluble in the usual solvents. 2 RNClz + 2 Ni(CO)4 + 2 [RNClzNi(CO)

The monoprotonated biguanides phenformin hydrochloride, buformin hydrochloride and metformin hydrochloride were investigated by 15 N NMR spectroscopy. The structure of all hydrochlorides is best described by a 1,3-diazabutadienic skeleton with three amino groups and its corresponding mesomeric forms
The dielectric behavior of a suspension of synchronized, spherical cells has been investigated in relation to the electrical parameters of certain cell structures. In the quasistatic approximation, Poisson's equations are solved for the respective diffusive media, and the local charge distributions
