Abstract

The reaction of the organolutetium complex (CGC′)LuCl ₃Li₂(THF), (1; CGC′ = [Me₂Si(3- pyrrolidinyl-1-η⁵-indenyl)(^tBuN)]^2-) with NaN(TMS)₂ provides a straightforward route to the halide-free organolutetium amido complex, (CGC′)LuN(TMS)₂(THF) (2). These new complexes were characterized by standard analytical methodology. The monomeric complex 2 crystallizes in the monoclinic space group P2₁/c with four molecules in a cell of dimensions a = 11.1566(6) Å, b = 14.9805(8) Å, c = 22.18007(12) Å, and β = 90.0620(10)°. Complex 2 is an active precatalyst for the intramolecular hydroamination/ cyclization of representative aminoalkenes with turnover frequencies as high as 205 h^-1 at room temperature.
