From SIR to BIR : Following the concept of the sterically induced reduction (SIR), the base‐induced reaction (BIR) has now been discovered. [Sm(AlMe 4 ) 3 ] reacts with the bulky base 1,3,5‐tricyclohexyl‐1,3,5‐triazacyclohexane (TCyTAC) in benzene to give [(TCyTAC) 2 Sm II (AlMe 4 ) 2 ] (see picture; Sm red, Al dark gray, N green, C light gray) and ethane, and is in competition with CH activation yielding [TCyTAC) 2 Sm{CH(AlMe 3 ) 3 }] and methane.
