摘要:
Synthesis of Fungicidal (1H‐1,2,4‐Triazol‐1‐yl‐methyl)silanes and ‐siloxanesThe synthesis of FlusilazoleTM(1a) was substantially improved by thorough exclusion of oxygen nucleophiles in the reaction of (chloromethyl)bis(4‐fluorophenyl)methylsilane with sodium 1H‐1,2,4‐triazolide. New α,α‐diaryl‐α‐(1H‐1,2,4‐triazol‐1‐yl‐methyl)siloxanes3were obtained firstly from diaryl(1H‐1,2,4‐triazol‐1‐yl‐methyl)silanols or ‐silanolates, which were prepared by different methods from the corresponding silanol hydrochlorides and further treated with functional, linear oligodimethylsiloxanes or secondly from α,α‐diaryl‐α‐(chloromethyl)siloxanes and 1‐(trimethylsilyl)‐1H‐1,2,4‐triazole. The siloxane4containing a triazolylmethyl group and additionally silicofunctional coupling groups could be synthesized by hydrosilyla
