sulfur and selenium heterocycles based on the consecutive cyclometallation of olefins, allenes, and acetylenes using alkyl and haloalkyl derivatives of Al and Mg in the presence of catalytic amounts of titanium and zirconium complexes to give the corresponding alumina- and magnesacarbocycles in situ, which, without further purification, were introduced into reaction with sulfur or selenium, leading to
在催化量的钛和锆络合物的存在下,使用Al和Mg的烷基和卤代烷基衍生物,基于烯烃,丙二烯和乙炔的连续环金属化,开发了一种一锅法用于合成五元硫和硒杂环的方法得到原位生成的相应的铝碳环和镁碳环,无需进一步纯化即可将其引入与硫或硒的反应中,从而生成各种四氢噻吩,噻吩,四氢硒吩和硒吩。
