The widely useful tributyltin hydride as catalyst (in the presence of NaBH 4 ) effects the radical chain lengthening of alkyl iodides with acrylonitrile or alkenes which contain, e.g. ketone aldehyde, ester or phenyl substituents. As reagent, tributyltin hydride enables a convenient synthesis of C ‐branched deoxy sugars. A sugar such as 1 , Y OH , is converted into a xanthogenate or thiourethane, which e.g., reacts with acrylonitrile to give 2 , R CH 2 CH 2 CN.
