Summary Reaction of dlphenyitm dlhydnde with dlphenyltm dxchlonde or diphenyltm dlbromlde m a 1 1 mole ratlo gwes good conversion to dlphenyltm chlonde

hydride and dlphenyltm bromxde hydnde, respectively Tnphenyltm hydnde with drphenyltm drchlonde or drphenyltm drbromrde in a 1 1 mole ratio gives fan conversion to the correspondmg hahde hyandes but less than m the case of drphenyltm dlhydnde Drphenyltm drhydnde reacts with dralkyltm dlchlonde m a 1 1 mole ratio to grve a preponderance of organotm chlonde hydride along with dlphenyltm drhydnd,o but no dlalkyltm dlhydnde However, tnphenyltm hydnde did not appear to react with dralkyltm dihahdes m a 1 - 1 mole rako to yield either the dralkyltm halide hydnde or the dralkyltm drhydnde. Reactions attempted between tnphenyltm hydnde and several tnalkyltin chlorides confirm the tendency of the hydnde hydrogen to become attached to the tnphenyltin morety rather than the tnalkyltm or the dlalkylchlorotm moieties

Introduction Consrderable work has been done on hahde-hydnde exchanges mvolvmg alkyltm hydrides and m partrcular butyltm hydrides [l-7]. Very little has been reported on comparable exchanges mvolvmg phenyltm hydndes Tl-us paper concerns the results of exchanges we have camed out between phenyltin hydndes and organotm hahdes ES].

Results andducussion Reactions of dlphenyltm dlhydrrde wrth diphenyltin drhairdes Reactions were carried out between drphenyltin drhydnde and dlphenyltm &halides in a 1 I 1 mole rat10 accordmg to eq 1 * To whomcorrespondence shouldbe addressed
