Organic lithium salts suitable for use in electrolytes for primary or secondary rechargeable batteries include de-localized bulky anions over Lewis acid fragments, typically BF3, and organic moieties. The organic moieties may be, for example, anions derived from fused nitrogen heterocycles (e.g. benze...
The decrease in D-->A bond lengths, previously reported for some Lewis acid/base complexes, in going from the gas to the solid phases is investigated by obtaining an accurate crystal structure of solid ND(3)BF(3) by powder neutron diffraction. The B-N internuclear distance is 1.554(3) ...
Understanding the formation of [3+2] and [2+4] cycloadducts in the Lewis acid catalysed reaction between methyl glyoxylate oxime and cyclopentadiene: a the... The formation of the formal [3+2] and [2+4] cycloadducts in the Lewis acid (LA) catalysed reaction of cyclopentadiene (Cp, 1)...
Lack of 1,3-syn-pentane interaction in the TS-b2 case, and the withdrawing effect of BF3 as a Lewis acid could explain this phenomenon. NBO analysis showed that the coordination site is crucial in the amount of interaction between the O atom of aldehyde moiety with the B atom of chiral ...
