Many of these compounds were toxic for example, tetra-methyl phosphorodiamidic fluoride (dimethylaminofluorophos-phine oxide (VII)) had a l.c. 50 of 0-1 mg./l. Unlike the phosphorofluoridate esters, however, they were devoid of myotic action.

The calculation of atomization energies of nonmolecular solids is summarized in Tables II for fiuorides. III for chlorides, IV for bromides, V for iodides, VI for oxides, VII for sulfides, and VIII for selenides. The successful application of Equation 2 to such a large number and variety of nonmolecular compounds strongly supports the coordinate covalent or coordinated polymeric model. It seems probable that more complex compounds such as sulfates and carbonates are also of this nature.

Ausgehend von 2-Phenyl- (VI) und 2-(2-Furyl)--7-oxid (VII) wird Lithiierung in der 6-Position beobachtet (Butyl-lithium, THF, — 65°). 

Boas et al. prepared and separated the meridional isomers of the [Co(ai-02)2] type complexes (oti-a2 represents the dianion of the dipeptide H2 i-a2> where ai is the N-terminal residue). Seven methods were used to prepare bis(dipeptidato)-cobaltate(III) complexes (i) by oxygenation of cobalt(II), (ii) from cobalt(II) carbonate, (iii) from sodium tricarbonatocobaltate(III), (iv) from hexaamminecobalt-(III) chloride, (v) from hexakis(urea)cobalt(III) perchlorate, (vi) from cobalt(III) hydroxide oxide, (vii) from triammine(glycylglycinato)cobalt(III). The methods starting from Co" gave more minor products, Na3[Co(C03)3] 3 H2O gave less, and cobalt(III) hydroxide oxide gave very little of these products. Thus, the method (vi) was prefered. The peptides used were gly-gly, L-ala-gly, gly-L-ala, L-leu-gly, gly-L-leu, L-phe-gly, gly-L-phe, L-ala-L-ala, L-ala-D-ala, L-leu-L-leu.

The hierarchy of nanomaterials contains the considerable list of various groups, such as, (i) fuUerenes and their derivatives, (ii) single wall carbon nanotubes (SWCN) (iii) multi walls carbon nanotubes (MWCNT) (iv) graphene (v) micro-electro-mechanical systems (MEMS) (vi) metal nano oxides (vii) quantum dots, and others. One can expect that in the near future this list will be extended owing to intensive work of experimentahsts.
