1,2,3-Trimethoxybenzene reacts with BF4Mn(CO)(5) in CH2Cl2 or ClMn(CO)
(5) in CF3CO2H then with HPF6 to afford 1,2,3-trimethoxybenzene mangan
ese tricarbonyl tetrafluoroborate 2a or hexafluorophosphate 2b, the X-
ray structure of which indicates an arene nonplanarity and an eclipsed
conformation of C1, C3 and C5 carbons; LiEt(3)BH, EtMgBr, and SiR(3)C
HLiCN (R = Me, i-Pr) additions occur mainly on the C5 eclipsed carbon
of complex 2a.
