Abstract
The synthesis of new mono- and disilacrown ethers ([k]O(l)Si(m): (k,l, m) = (8,3,1); (11,4,1); (16,6,2); (22,8,2)) was achieved by reacting P h2SiCl2 with HO-(CH2CH2O)n-H (n = 2, 3) in the presence of base. Varia tion of the later revealed that cations could act as templates and thu s orient the synthesis towards the mono- or the disilanes.
