Main group and transition metal-mediated phosphaalkyne oligomerizations

摘要: Abstract The first isolable phosphaalkyne was discovered by Becker, Gresser, and Uhl in 1981. Since this initial discovery, the chemistry of phosphaalkynes has continuously attracted attention. Several routes for preparation have been described they exist with a wide variety substituents. Phosphaalkynes are versatile ligands to transition metals, displaying range coordination modes. Under properly chosen conditions, readily undergo oligomerizations. Uncontrolled thermal reactions give rise mixtures cage compounds, whereas metal-mediated oligomerizations allow increased control, leading selectively products such as dimers A–C, trimers D–E, tetramers F–I or higher oligomers J–K. This review describes each type oligomerization focuses on mediated main group metals.
