Popis:	The titanium complex prepared from TiCl3 and NaBH4 in THF in the presence of 18-crown-6 promotes the catalytic hydroboration of carbon–carbon double bonds in alkenes, alkadienes and unsaturated ethers with NaBH4, giving sodium organoborates which can be converted into alcohols by oxidation with H2O2/CH3ONa. The reaction proceeds with high regio- and stereo-selectivities.
