| titleOfInvention | Production of organoborons |
| abstract | Organoboranes are made by reacting an organooxy boroxine of the formula (ROBO)3, wherein R is an organic group and the three R groups have a total number of carbon atoms not exceeding 30, with an organo aluminium compound. The reaction proceeds very readily at room temperature and the reaction is preferably performed at between 20 DEG C. and 50 DEG C. employing 3 to 4 moles of the organo aluminium compound per mole of the organooxy boroxine. The organooxy boroxine may be prepared by adding 1 to 2 moles of boric oxide per mole of an appropriate borate ester and reacting at temperatures up to 400 DEG C. and higher. Suitable organooxy boroxines are trimethoxy boroxine, triethoxy boroxine and corresponding compounds in which the group R is octyl, octadecyl, tricosyl, vinyl, propenyl, cyclohexyl, 1-hexynyl, phenyl or naphthyl. The organo aluminium compounds include trimethyl, triethyl and other trialkyls, tripropenyl, trihexenyl, tricyclopentyl, tricyclohexyl, tri-1-hexynyl, tribenzyl, triphenyl, trinaphthyl, dimethylethyl, diethylmethyl aluminium and other organo aluminium compounds such as diethylaluminium chloride, bromide, iodide or fluoride, ethyl aluminium dichloride and diethylaluminium hydride. Suitable solvents are hydrocarbons, ethers and tertiary amines. On completion of the reaction, the organoborane is removed by distillation and the aluminium alkoxide by-product is hydrolysed to release the alcohol residue which can be reacted with boric acid, boric oxide or borax and sulphuric acid to produce the borate ester, and the latter is readily converted back to the organooxy boroxine by heating with boric oxide. Reference has been directed by the Comptroller to Specification 815,140. |
