Abstract
[1191-15-7] C8H19Al (MW 142.22) InChI = 1S/2C4H9.Al.H/c2*1-4(2)3;;/h2*4H,1H2,2-3H3;; InChIKey = AZWXAPCAJCYGIA-UHFFFAOYSA-N (reducing agent for many functional groups; opens epoxides; hydroaluminates alkynes and alkenes) Alternate Names: DIBAL; DIBAL-H; DIBAH. Physical Data: mp −80 to −70 °C; bp 116–118 °C/1 mmHg; d 0.798 g cm−3; fp −18 °C. Solubility: sol pentane, hexane, heptane, cyclohexane, benzene, toluene, xylenes, ether, dichloromethane, THF. Form Supplied in: can be purchased as a neat liquid or as 1.0 and 1.5 M solutions in cyclohexane, CH2Cl2, heptane, hexanes, THF, and toluene. Handling, Storage, and Precautions: neat liquid is pyrophoric; solutions react very vigorously with air and with H2O, and related compounds, giving rise to fire hazards; use in a fume hood, in the absence of oxygen and moisture (see Lithium Aluminum Hydride for additional precautions); THF solutions should only be used below 70 °C, as above that temperature ether cleavage is problematic.
