Stepwise metalation and trapping, so called trans-metal-trapping (TMT), of anisole is studied using LiTMP as base and Ga(CH2SiMe3)3 as trap. The isolated "trapped" intermediate is also assessed in C-C bond forming reactions, highlighting the inherent advantages and remaining challenges of this system. The same base trap mixture is found to metalate N-Me bonds of the diamines TMEDA and PMDETA. Comparative studies replacing LiTMP by NaTMP have found significant alkali metal effects on the extent of both base-trap cocomplexation and onward reactivities of TMT products.
