Studies in Stereochemistry. VIII. The Effect of F-Strain on the Relative Base Strengths of the Isopropyl- and t-Butylamines

Stability Relationships Among Analogous Molecular Addition Compounds Of Group III Elements

“…Again, only a qualitative indication of dative-bond strength can be obtained in this manner. As a general rule (30), for two addition compounds of closely similar type and molecular weight, the less stable exhibits the higher saturation pressure. For addition compounds differing in molecular weight it is to be expected that the lighter would be the more volatile.…”

Aromatic Nucleophilic Substitution Reactions.

“…Their argument, that the intrinsic nucleophilic activity of the amines is modified by the steric effects of their alkyl groups, is convincing. Diisobutyl amine.................... Brown and coworkers (97,98,100) have demonstrated that the relative basic strengths of amines depend upon the acid (in the Lewis sense) which is used for reference. With a small reference acid, such as the proton, basicities are largely determined by the electronic influences of the alkyl groups upon the nitrogen atom, but with large reference acids both the electronic and the steric effects of the substituent alkyl groups are important.…”

Preparation of fluoride anion responsive poly(N-vinylcarbazole)-borane complexes

“…Boron-nitrogen complexes are well known compounds as reported in early works by Brown et al [39][40][41]. These compounds have been studied as valuable precursors for ceramics [42] such as boron nitride, and also as light emitting materials [43][44][45].…”
