Backbone Modified Small Bite-Angle Diphosphines: Synthesis, Structure and Regioselective Thermal Rearrangements of Os3(CO)10{μ-Ph2PCH(Me)PPh2}

Backbone-functionalised ruthenium diphosphine complexes for catalytic upgrading of ethanol and methanol to iso-butanol

“…An alternative approach could be deprotonation of the acidic backbone in dppm complex I but this tends to require somewhat forcing conditions and the use of strong bases ( n BuLi or MeLi). [54][55][56][57][58][59][60][61][62] Complexes 1-7 were synthesized as yellow solids in goods yields (typically >80%) and characterised by NMR spectroscopy, mass spectrometry and X-ray crystallography. The 31 P NMR spectrum of the trans-[RuCl 2 (dppen) 2 ] (Pre-Cat) gave a singlet at 15.3 ppm which upon functionalisation with these amines shifted upfield to ca.…”
