Rhodium(I) metallacycles based on alkylated-PTA scaffolds: Synthesis and evaluation as hydroformylation catalyst precursors

A series of rhodium(I) metallacycles based on alkylated PTA complexes were synthesised and fully characterised
using a range of spectroscopic and analytical techniques. These mononuclear Rh(I) complexes were evaluated in
the aqueous biphasic (water-toluene) hydroformylation of 1-octene, showing chemoselectivity to aldehydes
