Abstract: | The fluorination of MeAlN(2,6-i-Pr2C6H3)]31 using 1 and 2 eq., respectively, trimethyltin fluoride leads to the mono- and difluoro compounds, FAl(MeAl)2(N(2,6-i-Pr2C6H3))3]·2THF 2 and (FAl)2MeAl(N(2,6-i-Pr2C6H3))3]·3THF 3, where each methyl group can be selectively exchanged for terminal fluorine atoms (AlF). The reaction of 1 and 3 eq. of trimethyltin fluoride leads to the trifluoro compound FAlN(2,6-i-Pr2C6H3)]3·3THF 4 and Me2SnN(2,6-i-Pr2C6H3)]25 as a by-product. The core of compound 5 consists of a tin-nitrogen four-membered Sn2N2 ring. |
