1,3,4,5-Tetraethyl-2-methyl-1,3-diborolene (1) reacts with MX2 (M = Pd, Pt) and Na(C5H5) to give orange-red cyclopentadienyl(1,3-diborolenyl)palladium 3 and the yellow platinum complex 4, respectively. Bis(1,3,4,5-tetraethyl-2-methyl-1,3-diborolenyl)platinum (5) is obtained in low yield from 1, Na(HBEt3) and PtCl2 or from 1 and [(C2H4)PtCl2]2. 1H, 11B, and 13C NMR data of 3, 4, and 5 are in agreement with a sandwich structure. The 16e complex 5 is reduced by potassium to its mono- and dianion.
