Calculate Digit Verification of CAS Registry Number 90324-59:
(7*9)+(6*0)+(5*3)+(4*2)+(3*4)+(2*5)+(1*9)=117
117 % 10 = 7
So 90324-59-7 is a valid CAS Registry Number.

Contributions to the Chemistry of Boron, 165 Diisopropyl- and Di-tert-butylborane Derivatives

Hoebel, Ulrike,Noeth, Heinrich,Prigge, Helene

, p. 325 - 337 (2007/10/02)

Methods for the preparation of diisopropyl- and di-tert-butylboranes R2BX (X = F, Cl, Br, I, OR', SCH3, NH2, NHR', and NR'2) are described.They use the readily accessible (dimethylamino)diorganylboranes 2a, b which are conveniently obtained from the (dimethylamino)dioxaborolane 1a by reaction with (CH3)2CHMgBr and (CH3)3CLi, respectively.The influence of the bulky groups R on the reactivity of these boranes is demonstrated for a number of examples.
