- A half-sandwich 1,2-azaborolyl ruthenium complex: Synthesis, characterization, and evaluation of its catalytic activities
-
A half-sandwich 1,2-azaborolyl (Ab) ruthenium complex, (Ab-CCPh) RuCl(PPh3)2 (1), has been synthesized by treating RuCl2(PPh3)3 with lithium 1,2-azaborolide L-1, or by treating either RuCl2(PPh3)3 or RuHCl(PPh3)3 directly with 1,2-azaborole LH-1. It is evaluated as a suitable precatalyst in [2 + 2] cycloadditions of norbornene derivatives with DMAD and in atom transfer radical additions of halogenated compounds with olefins.

- METAL-OXIDE INDUCED REDOX CHAIN ADDITION OF TETRACHLOROMETHANE TO A CARBON-CARBON DOUBLE BOND
-
Formation of 1:1 adducts in the addition of tetrachloromethane to a terminal carbon-carbon double bond was investigated at 76-200 deg C.The redox chain addition reaction with 1-octene, electron-deficient alkenes and unconjugated aliphatic dienes induced by catalytic amounts of copper(I) or copper(II) oxides in conjugation with diethylamine or diisopropylamine afforded the corresponding 1:1 adducts up to in 85percent yields.Aliphatic 1,3-dienes underwent redox chain 1,4-addition giving isomeric 1,1,1,5-tetrachloro-3-alkenes.
