THE CONFORMATION OF MEDIUM-SIZED ORGANOSILICON HETEROCYCLES - 1ST EVIDENCE FOR THE EXISTENCE OF A BOAT-BOAT CONFORMATION IN A 12H-DIBENZO[D,G][1,3,2]DIOXASILOCIN
Fh. Clarke et al., THE CONFORMATION OF MEDIUM-SIZED ORGANOSILICON HETEROCYCLES - 1ST EVIDENCE FOR THE EXISTENCE OF A BOAT-BOAT CONFORMATION IN A 12H-DIBENZO[D,G][1,3,2]DIOXASILOCIN, Helvetica Chimica Acta, 76(4), 1993, pp. 1476-1480
X-Ray crystal-structure analysis of 2,4,8,10-tetrakis(1, )-6,6-dimethy
l-12H-dibenzo[dg][1,3,2]-dioxasilocin showed that its eight-membered o
rganosilicon heterocycle adopts a boat-boat (BB) conformation in the s
olid state (Figs. 2 and 3).
