Abstract

Who is the man behind the aluminum mask? The first Group 4 Lewis acid stabilized alkylidyne (2; see picture) is generated by incomplete addition of trimethylaluminum across a {Ti≡CtBu} moiety (1; PNP = [2-{P(CHMe 2)2}-4-MeC6H3]2N -). In contrast, B(OCH3)3 completely adds to 1 by B-O bond cleavage to afford an unusual alkylidene. Complex 2, a masked alkylidyne titanium compound, also ring-opens pyridine. (Chemical Equation Presented).
