Nonuniqueness of semidirect decompositions for semidirect products with directly decomposable factors and applications for dihedral groups
Nonuniqueness of semidirect decompositions of groups is an insufficiently
studied question in contrast to direct decompositions. We obtain some results
about semidirect decompositions for semidirect products with factors which are
nontrivial direct products. We deal with a special case of semidirect product
when the twisting homomorphism acts diagonally on a direct product, as well as
for the case when the extending group is a direct product. We give applications
of these results in the case of generalized dihedral groups and classic
dihedral groups . For we give a complete description of
semidirect decompositions and values of minimal permutation degrees
Copper-Catalyzed Arylation of 1\u3cem\u3eH\u3c/em\u3e-Perfluoroalkanes
A general method has been developed for arylation of readily available 1H-perfluoroalkanes. The method employs aryl iodide and 1H-perfluoroalkane reagents, DMPU solvent, TMP2Zn base, and a copper chloride/phenanthroline catalyst. Preliminary mechanistic studies are reported
