Abstract
The reactivity of the palladium (II) bis (phosphine) complexes, (Ph 2 P(CH 2 ) n PPh 2 )PdCl 2 (n=1-6) toward the octahydrotriborate (1−) anion, [B 3 H 8 ] − , has been investigated. For n=1-4, the metallaborane (Ph 2 P(CH 2 ) n PPh 2 ) Pd(B 3 H 7 ) is produced, although the yield depends upon the organic chain length of the phosphino ligand and is maximized when n=2. Our observation that no reaction occurs between the [B 3 H 8 ] − anion and (bis(diphenylphosphino) pentane)- or (bis(diphenylphosphino) hexane)-palladium (II) dichloride leads us to examine the structure of these starting materials
The trans-(bis(diphenylphosphino)hexane)palladium(II) dichloride dimer shows a reactivity towards octahydrotriborate(1-) anion, with a maximum yield when n=2, and a dependence
