… by low-valent nickel establishes the use of main-group ions as coordination site
protection agents for transition-metal centers. As described by J. S. Figueroa and coworkers in their Communication on page 3473 ff., Tl(I) coordination provides a route to
the preparation of a coordinatively unsaturated nickel tris-isocyanide complex. Thallium
functions as a protecting group towards Lewis bases and is readily removed upon
addition of halide ions.
