Conclusions
-
1.
The action of C2H5ONa or t-C4H9ONa on C5H5CoB9H9C2HCHO leads to splitting of the CHO group with the formation of C5H5CoB9H9C2H2.
-
2.
The reaction of C5H5CoB9H9C2HCHO with Grignard reagents proceeds stereoselectively, and leads to diastereoisomeric secondary alcohols.
-
3.
The action of LiAlH4 and H2AlCl on C5H5CoB9H9C2HCH(OH)R causes hydrogenolysis of the CHOH group with the formation of C5H5CoB9H9C2HCH2R.
