The kinetics and mechanism of ligand substitution reactions of square-planar platinum(II) dimethyl sulfoxide complexes have been exhaustively studied (173), and these workers conclude that the cis and trans influences and the trans effects of Me2SO and ethylene are similar in magnitude whereas the cis effect of Me2SO is about 100 times as large as that of ethylene. The results for reaction (5), where the stability constants, Kt, are reported to be 1.5 x 108 (L = S-Me2SO) and 4.5 x 108 (L = ethylene) corroborate this analogy (213). [Pg.150]

The classical route for producing 2,2 -dipyridyl consists in the dehydrodimerization of pyridine on Raney-Ni using a process developed by the Imperial Chemical Industries [63AHC(2)179 68CI(L)49, 80MI4]. 2,2 -Bipyridyl reacts with ethylene bromide to give l,l -ethylene-2,2 -bipyridylium bromide (diquat). The production of one ton of the diquat (which is widely used as a herbicide) requires 1.2 tons of pyridine [Eq.(17)]. [Pg.190]

Groups of 30 male and 30 female B6C3F] mice were administered 4 mmol/L ethylene dibromide (purity > 99%), a dose equivalent to 116 mg/kg bw for males and 103 mg/kg bw for females) in distilled drinking-water for 450 days. A control group of 60 males and 60 females was given distilled drinking-water. Ethylene dibromide induced squamous-cell carcinomas of the forestomach in 26/28 males and 27/29 females and squamous-cell papilloma of the oesophagus in 3/30 females compared with none in 45 male and 50 female controls (Van Duuren et al., 1985). [Pg.643]

Herbicides. A major outlet for pyridine (20-30 million lb/yr worldwide) is in the manufacture of the desiccant herbicides and aquatic weedkillers, such as l,l -ethylene-2,2 -dipyridihum dibromide, known as Diquat and I. l -dimethyl-4,4 -dipyndihum drchlonde (or dibromrde or dimethylsullate). known as Paraquat. ... [Pg.1385]
