Reaction of Cp2TiR (R alkyl) with 2-substituted-pyridines and with quinolines leads to α-metallation of these ligands with formation of triangular titanocylcles containing TiIII. Proof of the metallation at the α-position comes from reactions of the complexes formed with I2 and D2O/DCI which yield the corresponding iodo- and deutero-pyridine and -quinoline derivatives. Reaction of Cp2TiR with the

Efficient and selective: FrustratedLewispairs based on BF3⋅OEt2 and LiCl‐complexed tmpMg or tmpZn amides (tmp=2,2,6,6‐tetramethylpiperidyl) allow the efficient and regioselective metalation of various functionalized N heterocycles (see scheme for examples). Moreover, such metalations carried out in the presence or absence of BF3⋅OEt2 enable a complete switch of regioselectivity, thus allowing complementary
