✦ Synopsis

Several reoent paper8 have dealt with the interaotion of diethylrino and eino halidee(" 2, with apeoial emphaeie on the nature of the epeoiee present in ether eolvente (3-6) . In the preeent oommunioation we rich to report on eome eapeote of the ohemietry of uneolrated alkylnine halides. The title oompounde are obtained aooordilyl to (I) by heating the appropriate sino halide and dialkyleino (100 $ exoeee) at 70' till the first hem completely dierolved (lo-20 min.), removing the exoeme of dialkylzino in vaouo and reoryetallieing the eolid reeidue from g-pentane*. B2Zn + %X2* 2 BZnX (I) Ethyleino halides eo obtained (Table I) are oolourleee, oryetalline aolide. EtZnCl and EtZnRr chow a sharp melting point and give perfectly clear eolutione in aprotic, apolar rolvente euoh ae E-hexane or toluene. * Satisfaotory analyres have been obtained for all oompounde reported.
