Dipole interactions and diffusion of μ meson in copper

The dipole relaxation rate and the diffusion coefficient of μ⁺-meson in copper are measured at different temperatures. The activation energy of μ⁺-meson in a crystal of copper is determined.     

Synthesis of 1-substituted 2, 5-bischloromethylpyrrolidines

A number of 1-substituted 2, 5-bischloromethylpyrrolidines, cyclic analogs of bis-Β-chloroethylamine, have been synthesized. The previously unreported 1-phenyl- and 1-benzyl-2, 5-bis(N-cycloalkylaminomethyl)pyridines and their methiodides have been obtained.     

Acylation of thermal acetylenes

Conclusions A new method was developed for obtaining acetylenic ketones via the reaction of terminal acetylenes with the acid chlorides of aliphatic and aromatic acids in the presence of catalytic amounts of CuI without using Pd compounds.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1158–1159, May, 1981.
