Abstract
Efficient catalysts for the dehydrocoupling or dehydropolymerisation of H(3)B center dot NMe(x)H((3-x)) (x = 1, 2) have been developed by variation of the P-Rh-P angle in {Rh(Ph(2)P(CH(2))(n)PPh(2))}(+) fragments (n = 2-5).

Robertson, K. Lee and I. Manners, Chem.–Eur. J., 2010, DOI: 10.1002/chem.201003397. 26 After 2 hours a small amount (B5%) of a new boron-containing product was observed by 11B NMR spectroscopy, with the remainder being unreacted H3BNMeH2. Studies are underway to characterise this material. |
