Air & Water Reactions

Insoluble in water.

Reactivity Profile

A brominated alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Fire Hazard

The flash point of 3-Bromo-2,2-bis(bromomethyl)propanol has not been determined, but 3-Bromo-2,2-bis(bromomethyl)propanol is probably combustible.

Synthesis and copolymerization of azidomethyl-substituted oxetanes: the morphology of statistical block copolymers

[Figure not available: see fulltext.] 3,3-Bis(azidomethyl)oxetane and 3-azidomethyl-3-methyloxetane were obtained by bromination of pentaerythritol and metriol with a mixture of hydrobromic, acetic, and sulfuric acids, followed by cyclization in the presence of a phase-transfer catalyst TBAB, with the formation of oxetane ring and replacement of bromide substituents with azide ions. The copolymerization reaction of 3,3-bis-(azidomethyl)oxetane and 3-azidomethyl-3-methyloxetane was performed in the presence of a catalytic system prepared from triisobutylaluminum and water. The methods of small-angle and wide-angle X-ray diffraction analysis were used to determine the amorphous-crystalline and domain structures of the synthesized copolymers. We also present data about conformational and relaxation transitions in these statistical copolymers.

Synthesis and structural characterization of ruthenium(II) complexes bearing phosphine-pyrazolyl based tripod ligands

Phosphine-pyrazolyl based tripod ligands ROCH2C(CH2Pz)2(CH2PPh2) (R = H, Me, allyl; Pz = pyrazol-1-yl) were efficiently synthesized and characterized. Reactions of these ligands with [Ru(η6-p-cymene)Cl2]2 afforded complexes of the type [Ru(η6-p-cymene)Cl2](L) (6-8) in which the ligands exhibit κ1-P-coordination to the metal center. Complex [Ru(η6-p-cymene)Cl2{Ph2PCH2C(CH2OH)(CH2Pz)2}] (6) underwent chloride-dissociation in CH2Cl2/MeCN to give complex [RuCl(η6-p-cymene){κ2(P,N)-Ph2PCH2C(CH2OH)(CH2Pz)2}][Cl] (9). Complexes 6-9 demonstrated poor to moderate catalytic activity in the transfer hydrogenation of acetophenone. All these complexes were fully characterized by analytical and spectroscopic methods and their molecular structures were determined by X-ray crystallographic study.
