This reagent is generated by treating 9-BBN with α-pinene. [2] This sterically crowded chiral trialkylborane can stereoselectively reduce aldehydes in what is known as the Midland Alpine borane reduction, or simply the Midland reduction. [3] C 8 H 12 B-pinanyl + RCDO → C 8 H 12 BOCHDR + (+)-d-pinene. Hydrolysis of the resulting borinic ester ...
In the same year, M. M. Midland discovered B-3-alpha-pinanyl-9-BBN as the reducing agent, which could be easily available by reacting (+)-alpha-pinene with 9-BBN. The new reducing agent was later commercialized by Aldrich Co. under the name Alpine Borane and the asymmetric reduction of carbonyl groups with either enantiomer of Alpine-Borane is ...
9-Borabicyclo[3.3.1]nonane or 9-BBN is an organoborane compound. This colourless solid is used in organic chemistry as a hydroboration reagent. The compound exists as a hydride-bridged dimer, which easily cleaves in the presence of reducible substrates. [1] 9-BBN is also known by its nickname 'banana borane'. [2]

The only professional review came from Consequence of Sound.Reviewer Katherine Flynn, after criticising the band's previous album, 2009's Battle for the Sun, which she wrote "didn't feel as urgent, or as true, as anything that had come before [in Placebo's canon]", saw B3 as a "[return] to their loud, largely minor-key hijinks" and writing that the EP "kicks", citing the ending track "Time Is ...
