Non-covalent bonded 1D-3D supramolecular salts from tert?butylamine and organic acids

Cocrystallization of the widely available simplest voluminous primary amine, tert?butylamine, with a set of acids got a total of 14 salts, which have been featured by XRD technique, Infrared spectra and elemental analysis. Their melting points were also surveyed. Their structural and supramolecular aspects are analyzed in detail. All compounds are ionic, with H-transferring to the NH2 of the tert?butylamine. The results unveil that among all the studied crystals the NH2 in L are protonated when the acids are deprotonated, the crystal packing is interpreted via the strong N–H?O H-bond from the NH3+ and the deprotonated acids. Apart from the N–H?O H-bond, the O–H···O H-bonds were also existed at 6 and 12. Salts 1 - 2 had the N–H?S H-bond. The N–H···Cl H-bond existed in 7. Further view of the crystal packing told that a different array of additional CH3···S, O···Cl, S···S, CH3···C, CH3···CH3, C–H···O/CH3···O, CH2···Cl, CH···N, CH3···π and π···π contacts help the stabilization and expansion of the whole structures. For the synergism of the various nonbonding contacts these structures had the hetero supramolecular synthons. Some classical synthons of R22(8), R42(8), R43(10) and R44(12), commonly present in solids of organic acids with amine, were again shown to be created in making these H-bonding nets.

SYNTHESIS OF STERICALLY HINDERED SECONDARY AMINOETHER ALCOHOLS

Severely sterically hindered secondary aminoether alcohols are prepared by reacting organic carboxylic, organic carboxylic acid halides, acid anhydrides or a ketene with an alkyl, alkaryl or alkylhalo sulfonate to yield a sulfonic. Carboxylic anhydride compound which is then reacted with a dioxane to cleave the ring of the dioxane, yielding a cleavage product which cleavage product is then aminated with an alkylamine and hydrolyzed with base to yield the severely sterically hindered secondary aminoether alcohol.

IMINOPHOSPHORANE-MEDIATED TRANSFORMATION OF TERTIARY ALCOHOLS INTO t-ALKYLAMINES AND THEIR N-PHOSPHORYLATED DERIVATIVES

Novel azidation of tertiary alcohols by means of trimetylsilyl azide in the presence of boron trifluoride etherate has been worked out.The Staudinger reaction of crude azides with triethyl phosphite affords the corresponding iminophosphoranes which can be directly transformed into diethyl N-(t-alkyl)phosphoroamidates or t-alkylamine tosylates.
