Straightforward synthesis of novel cyclic metallasiloxanes supported by an N,C,N-chelating ligand
Original language description
The reaction of an N,C,N-intramolecularly coordinated tin(IV) carbonate LSn(Ph)(CO3) (1) and antimony(III) and bismuth(III) oxides (LMO)(2) (where M = Sb (2), Bi (3) and L = C6H3-2,6-(CH2NMe2)(2)) with (HO) SiPh2(O)SiPh2(OH) in 1 : 1 (in the case of 1) or 1 : 2 molar ratio (in the cases of 2 and 3) gave the metallasiloxanes cyclo-LSn(Ph)(OSiPh2)(2)O (4) and cyclo-LM(OSiPh2)(2)O (where M = Sb (6) and Bi (7)) containing six-membered MSi2O3 rings. Alternatively, the compounds 4, 6 and 7 can be also prepared reacting Ph2Si(OH)(2) and compounds 1, 2 and 3, respectively, in the molar ratio of either 2 : 1 (for 4) or 4 : 1 (for 6 and 7). The reaction of Ph2Si(OH)(2) with 1 in 1 : 1 molar ratio gavecyclo-Ph2Si(OSnL(Ph)O)(2)SiPh2 (5) containing an eight-membered Sn2Si2O4 stannasiloxane ring. The analogous eight-membered stibasiloxane derivative cycloPh(2)Si(OSbLO)(2)SiPh2 (8) was obtained as well, while attempts to synthesize the bismuth analogue failed. Compounds 1-3 react with the siloxane cy
