The reductive cyclisation of 3-chloropropyliodo(methyl)arsine and 3-chloropropyliodo(phenyl)arsine with sodium in tetrahydrofuran affords the four-membered alicyclic tertiary arsines 1-methylarsetan and 1-phenylarsetan respectively. The five-membered homologues 1-methyl- and 1-phenyl-arsolan may be prepared similarly from the corresponding 4-chlorobutyliodo-methylarsine and -phenylarsine.
在四氢呋喃中用钠对3-氯丙基碘(甲基)ar和3-氯丙基碘(苯基)ar进行还原环化,分别得到四元脂环族叔a基1-甲基1-烷和1-苯基ar烷。可以类似地由相应的4-氯丁基碘-甲基ar和5-苯基ar制备五元同 型1-甲基-和1-苯基-sol。
