✦ Synopsis


9-borabicyclo [3.3.1]nonane, A Commercially Available Reagent, Is The Most Versatile Hydroborating Reagent To Synthesize Organoboranes (b-r-9-bbn). The Reagent Exhibits Remarkable Regio-, Chemo-, And Stereoselectivity During Hydroboration Reactions. The Organoboranes Can Be Converted To C-h, C-o, C-n, C-s, C-halogen, C-metal And Above All C-c Bonds. In Addition, The Suitable Substituted / Unsaturated R Of B-r-9-bbn Can Be Utilized To Produce Dienes, Enynes, Allenes Etc. With Defined Stereochemistry. 9-bbn's Derivatives Have Been Elegantly Used For The Asymmetric Reduction Of Ketone Moiety. Diels-alder And Suzuki Reactions Have Expanded The Utility Of 9-bbn For The Synthesis Of A Variety Of Organic Compounds Required For Industry. Consequently, This Vast Field In The Form Of A Book Will Be Helpful To Synthetic Organic Chemists For Easy Access To Literature, Required For Chemical Transformations.

## Abstract [^3^H]lithium 9‐boratabicyclo[3.3.1]nonane, at specific activity of 52–55 Ci/mmol, was synthesized by reduction of B‐OMe‐9‐BBN with lithium tritide. Its reducing characteristics were illustrated by the synthesis of [17‐^3^H] estradiol, [2‐^3^H] dihydrotetrabenazine and 1‐(hydroxy[^3^H]m
