193. Photoformation of (Z)-Isomers in Diarylazomethines. Part IV. Direct and Sensitized Photoisomerization of Pyridyl Analogues of Benzylidene-aniline and Absorption Spectra of their (Z)-Isomers
Maeda, Koko,Fischer, Ernst
, p. 1961 - 1965 (1983)
UV irradiation of solutions of the (E)-isomers of five (out of the possible six) monopyridyl analogues at reduced temperatures results in extensive (80-90percent) conversion into the corresponding (Z)-isomers.The process is reversible both thermally and photochemically.The (Z)-isomers are stable at temperatures below -80 deg, and their absorption spectra were estimated.Biacetyl-photosensitized (E)->(Z) isomerization was observed, with (Z)-contents of ca. 70percent at the photostationary state.

Heterocyclic imines provide biaryl products by a two-step transformation. The first transformation involves a Diels–Alder reaction with a multiply protonated imine to give a tetrahydroquinoline product, whereas the second step involves oxidation with elem
Controlled Single and Double Iodofluorination of Alkynes with DIH- and HF-Based Reagents
Pfeifer, Lukas,Gouverneur, Véronique
supporting information, p. 1576 - 1579 (2018/03/23)
A novel protocol for the regio- and stereoselective iodofluorination of internal and terminal alkynes using 1,3-diiodo-5,5,-dimethylhydantoin and HF-based reagents is disclosed. This approach is used to prepare a fluorinated tamoxifen derivative in two steps from commercially available starting materials. A facile method enabling controlled regioselective double iodofluorination of terminal alkynes is also presented.

Diels-Alder reactions have been accomplished with ethylene as the dienophile through the use of inverse-electron demand Diels-Alder chemistry. As a key aspect of the chemistry, the dienes are part of tri- or dicationic superelectrophilic systems. Theoreti
Palladium(II) complexes containing N,N′-bidentate imine ligands derived from picolinaldehyde and substituted anilines: Synthesis, structure and polymerisation of methyl methacrylate
Park, Suhyun,Lee, Jaegyeong,Jeong, Jong Hwa,Lee, Hyosun,Nayab, Saira
, p. 82 - 89 (2018/06/01)
Palladium(II) complexes, LnPdCl2 (Ln = LA–LI), with N,N′-bidentate imine ligands derived from picolinaldehyde and substituted anilines have been synthesized and structurally characterized. Molecular structures revealed a distorted square plane geometry around Pd(II) centre in LnPdCl2 (Ln = LA–LC) obtained via coordination with pyridine and imine nitrogens and two chloro ligands. Pd(II) complexes LnPdCl2 (Ln = LA–LI) initiate polymerisation of methylmethacrylate (MMA) in the presence of modified methylaluminoxane (MMAO). The complex LIPdCl2 (of which the ligand was N-furfuryl substituted) showed the highest catalytic activity for the polymerisation of MMA with an activity of 7.08 × 104 g PMMA/mol·Pd·h at 60 °C. All the complexes yielded syndio-rich poly(methyl methacrylate) (PMMA) ([rr] = 0.70). Notably, the substituents on the imine moiety of the iminopyridine fragments affects the activities towards MMA polymerization, whereas the stereoselectivities remained unchanged.
