The reaction of phosphorus(III) esters with pinacolborane generates phosphines via the action of an NHC-copper(I) catalyst. This gives access, within minutes, to 12 P–H bonded species, including secondary and primary phosphines as well as PH₃, in excellent conversions. These phosphines can be subsequently applied in the copper(I)-catalyzed hydrophosphination of heterocumulenes in a telescoped, one-pot fashion. This approach yielded 12 phosphaureas, 3 phosphaguanidines, and 2 phosphathioureas in moderate to excellent yields without the need to handle toxic, pyrophoric, or gaseous P–H bond containing compounds. The crystal structures of two of the phosphaureas, PhP(C(O)NHPh)₂ and P(C(O)NHPh)₃, are presented.

用于一锅 P-H 键形成和杂聚烯氢膦化的铜 (I) 平台

磷 (III) 酯与频哪醇硼烷的反应通过 NHC-铜 (I) 催化剂的作用生成膦。这可以在几分钟内获得 12 种 P-H 键合物质，包括二级和一级膦以及 PH ₃，并具有出色的转化率。这些膦可以随后以伸缩的一锅方式应用于铜 (I) 催化的杂枯烯的氢膦化反应。这种方法以中等至优异的产率产生了 12 种磷脲、3 种磷胍和 2 种磷硫脲，而无需处理有毒、发火或气态的含 P-H 键化合物。介绍了两种磷脲 PhP(C(O)NHPh) ₂和 P(C(O)NHPh) ₃的晶体结构。
