This paper reports the results of an FT-IR and NIR study of N-methylformamide in carbon tetrachloride solution in presence of ethers as the O-electron donors, i.e., diethyl ether (DEE), diisopropyl ether (DiPE), methyl t- -butyl ether (MtBE), dibutyl ether (DBE), dipentyl ether (DPE), tetrahydrofuran (THF) and tetrahydropyran (THP). The spectroscopic characteristics of the N-H???O hydrogen bonded complexes are given. In addition, the equilibrium constants for 1:1 complex formation were determined at 25?C using Mid-IR and NIR measurements.

In the solvents 1,2-dimethoxyethane (DME), 1,2-diethoxyethane (DEE), tetrahydrofuran (THF), and dioxane, potassium reacts much more readily with fluorene than does sodium or lithium. Lithium is generally more reactive than is sodium. The order of effectiveness of the ethers is DME > DEE ≈ THF > dioxane. Although practically no reaction of these metals with fluorene occurs in toluene, the addition of small amounts of these ethers to toluene does accelerate such reaction. All three organometallic compounds are soluble in refluxing and cold (22°) DME, THF, and DEE except the 9-fluorenyllithium, which precipitates largely from cold DEE. The results are explained in terms of the relative electropositivities of the metals, their size, and the structure of the ethers. It is suggested that these ethers actually participate in the formation of the organometallic compound from the metal.Sodamide and lithium amide react as readily as or more readily than the metals with fluorene in DME to produce the organometallic compounds.Diphenylmethane and triphenylmethane react reasonably well with potassium in DME, but too slowly with lithium and sodium to be useful.

Critical Temperatures

The gas-liquid critical temperatures, Tcm, of some mixtures of the electron donors, triethylamine, diethyl ether and diisopropyl ether with n-alkanes, benzene and hexafluorobenzene are reported. By using the van der Waals one-fluid model, an interaction energy parameter, ξ, has been calculated for each mixture from the values of T°m. The values of ξ for the n-alkane+electron donors are fairly close to unity, indicating that, as would be expected, there are no strong specific interactions between the unlike molecules. The values of ( for the electron donors with benzene give no definite indication of specific interactions. On the other hand, values of ξ for the electron donors with hexafluorobenzene indicate a specific interaction between the unlike molecules. These conclusions are discussed in relation to those reached from a consideration of other thermodynamic data.

Tert Butanol

[Li(tmed)]3[Sm(CH3)6] reacts with tert-butanol in diethyl ether to give [Li5Sm(O–t-C4H9)8] (1), the structure of which has been elucidated by X-ray structure analysis. 1 crystallizes tetragonally with a = 1703(4) and c = 3178(1) pm, space group P41212, Z = 8. The structure was refined to R = 0.042 for 4082 observed reflections (Fo > 6σ(Fo)).
