A novel set of linear α-olefin trimerisation pre-catalysts is presented. The R3TACCr(OTf)3 (R3TAC = 1,3,5-trialkyl-1,3,5-triazacyclohexane) complexes produce an active system after facile activation with less than 10 equivalents of trialkylaluminium

We report the C4-selective C–H alkylation of carbazole derivatives furnished with a pyrimidine directing group at N9. This was realized using ruthenium catalyzed σ-activation methodology, whereby C–H activation at C1 enables the interaction of t

A catalytic meta selective C-H alkylation of arenes is described using a wide range of α-halo carbonyls as coupling partners. Previously unreported primary alkylations with high meta selectivity have been enabled by this methodology whereas using st
