Synthesis of the new bulky phosphine ligand di-(1‑adamantyl)-2-trifluoromethyphenylphosphine is reported, which coordinates with the trifluoromethyl group projected toward the metal center and exhibits a % of 47.3%. Well-defined gold-(I) derivatives demonstrate higher catalytic activity for the cycloisomerization of 4-fluoro--(prop-2-yn-1-yl)-benzamide than di-(1‑adamantyl)-2-biphenylphosphine (AdJohnPhos) and di-(1‑adamantyl)-phenylphosphine analogues.
报道了新型大位阻膦配体二（1-金刚烷基）-2-三氟甲基苯基膦的合成，该配体与朝向金属中心的三氟甲基配位，其占有率为47.3%。结构明确的金（I）衍生物对4-氟-（丙-2-炔-1-基）-苯甲酰胺的环异构化反应表现出比二（1-金刚烷基）-2-联苯膦（AdJohnPhos）和二（1-金刚烷基）-苯基膦类似物更高的催化活性。
