Hexahomotrioxacalix[3]arene: a scaffold for a C3-symmetric phosphine ligand that traps a hydrido-rhodium fragment inside a molecular funnel
Abstract
Stereoselectivity around an H–Rh–CO fragment has been realized by reaction of the hexahomotrioxacalix[3]arene-derived triphosphine 4 with [Rh(acac)(CO)2]; the resultant trigonal bipyramidal complex has the Rh–H bond directed inside the cavity.
