ScholarBank@NUS Repository. https://doi.org/10.1021/om0105627 | Abstract: | The new bulky silicon-containing ditin precursor p-(RCl2SnCH2SiMe2)2C6H 4 (R = CH2SiMe3 (4)) has been synthesized and further reacted to form a unique double ladder {[p-(R(Cl)SnCH2SiMe2)2C6H4 ]O}4 (6). The two layers within 6 are twisted with respect to one another, resulting in a helical motif and a total absence of molecular symmetry so that there are eight chiral tin atoms within the system. The structure is compared to the double ladder {[m-(R(Cl)SnCH2CH2)2C6H4] O}4 (11), which was prepared from the less sterically demanding ditin precursor m-(RCl2SnCH2CH2)2C6H 4 (10). The two layers within 11 are parallel, and the molecule contains only two kinds of tin atom. | Source Title: | Organometallics | URI: | http://scholarbank.nus.edu.sg/handle/10635/93786 | ISSN: | 02767333 | DOI: | 10.1021/om0105627 |
