The nature of the paramagnetic centers of macromolecules with a system of conjugated C=C bonds
Springer Science and Business Media LLC - Tập 20 - Trang 1304-1308 - 1971
A. A. Berlin, G. A. Vinogradov, A. A. Ovchinnikov
NMR study of mono- and dilithium derivatives of alkyl and arylstannanes
Springer Science and Business Media LLC - Tập 53 - Trang 2327-2329 - 2004
P. A. Chugunov, N. A. Troitskii, K. S. Nosov, M. P. Egorov, O. M. Nefedov
Element-centered mono- and dianions of alkyl- and arylstannanes were studied by NMR spectroscopy. The 13C and 119Sn NMR chemical shifts for the dianions R2SnLi2 (R = Ph, Et) were measured for the first time.
Synthesis of N-vinyl derivatives of 2-methyl- and 4(5)-methylimidazoles
Springer Science and Business Media LLC - Tập 36 - Trang 1973-1975 - 1987
T. N. Mamashvili, N. A. Keiko, I. D. Kalikhman, E. S. Domnina, N. P. Glazkova, M. G. Voronkov
The reaction of 2-methyl and 4(5)-methylimidazoles with acetylene in the presence of Gu2Cl2 leads to the corresponding N-vinyl derivatives. 1-Vinyl-4(5)-methylimidazole is formed as a mixture of two isomers differing in the position of the methyl group.
Bromination of terphenyls
Springer Science and Business Media LLC - Tập 20 - Trang 2695-2696 - 1971
S. V. Zakharova, E. P. Kaplan
Mutual effect of atomic groups and spectra of acyloxydialkylboranes and other acylates
Springer Science and Business Media LLC - Tập 21 - Trang 1151-1153 - 1972
P. P. Shorygin, B. V. Lopatin, O. G. Boldyreva
30-Electron cationic iron- and cobalt-containing triple-decker complexes with a central cyclopentadienyl ligand. The first synthesis of the parent triple-decker iron complex with cyclopentadienyl ligands, [(η-C5H5)Fe(μ-η:η-C5H5)Fe(η-C5H5)]PF6
Springer Science and Business Media LLC - Tập 48 - Trang 1352-1355 - 1999
A. R. Kudinov, A. A. Fil'chikov, P. V. Petrovskii, M. I. Rybinskaya
The parent 30-electron triple-decker iron complex with cyclopentadienyl ligands, [(η-C5H5)Fe(μ-η:η-C5H5)Fe(η-C5H5)]PF6 (1), was prepared for the first time by visible-light irradiation of ferrocene and [(η-C5H5)Fe(η-C6H6)]PF6 in CH2Cl2 at 0 °C. An analogous reaction performed with the use of (η-C5H5)Co(η-C4Me4) (2) instead of ferrocene afforded the thermally labile 30-electron cationic iron-cobalt...... hiện toàn bộ
PMR spectra of monosubstituted cobalticinium salts
Springer Science and Business Media LLC - Tập 35 - Trang 1530-1532 - 1986
A. V. Malkov, E. V. Leonova, P. V. Petrovskii
Thermochemical study of liquid and solid organosilicon compounds
Springer Science and Business Media LLC - - 1986
M. G. Voronkov, V. A. Klyuchnikov, T. F. Danilova, A. N. Korchagina, V. P. Baryshok, L. M. Landa
A new synthesis of spiro-fused 1,4-benzothiazines
Springer Science and Business Media LLC - - 2001
A. V. Lesin, O. Ya. Borbulevych, S. V. Kurbatov, A. E. Ruzhnikov, M. Yu. Antipin, L. P. Olekhnovich
A new preparative procedure was developed for the synthesis of spiro-fused 1,4-benzothiazines by thermal heterocyclization of S-benzyl and S-phenacyl derivatives of o-indothiophenol.
