Trimer Trimethylamine

Effect of Concentration and CO Pressures on the Ruthenium Carbonyl-Trimethylamine WGSR System. As shown in Figure 1, the RU3(CO) 2/NMe3 WGSR system demonstrates a nearly first-order rate dependence on CO pressure at 0.5 mM Ru3(CO) 2 concentration. (Throughout this discussion, the total ruthenium carbonyl concentration is expressed as moles Ru3(00) 2 added per liter of solution this should not be construed to be the actual solution concentration of the trimer under operating conditions.) Here the initial rates of H2 production are 14.6 mmol /hr at 415 psi CO and 46.0 mmol /hr at 1200 psi. Thus, within experimental uncertainty, a threefold increase in CO pressure leads to a threefold increase in rate. 

Limited theoretical studies (31, 89) on the electron-deficient beryllium derivatives have been interpreted to imply that extensive Be—Be bonding occurs. If such bonding does occur, the increased bond length observed in the phenylethynyl(methyl)beryllium trimethylamine adduct takes on additional significance since the Be—Be distance in this derivative is increased by almost 0.3 A over that observed in dimethyl-and diethylberyllium. Moreover, if cyclic trimers are formed, then increased metal-metal distances would be likely, thus reducing the probability of stabilization of the bridged system by Be—Be bonding. Additional studies will be required both on structures and of spectroscopic properties of the species to answer these questions.
