Several rhodium(I) complexes containing chiral phosphine, (+) DIOP, (+> BINAP, (S,S) CHIRAPHOS, and (S)(R) BPPFA, have been found to be effective as catalyst for the asymmetric hydrobomtion of pm&h-al alkenes with catecholborane (1,3,2benzodioxaborole) to give optically active 2-alkyl-1,3,2-benzodio
## Abstract (2β(1,3βDithianyl))myrtanylborane (MDBH~2~), a stable asymmetric monoalkylborane, was converted into deuterated or tritiated analogues used to prepare enantiomeric labelled alcohols from 1βphenylcyclopentene with a high isotopic enrichment (90β95% for deuterium; 86β89% for tritium) and
