Triisopropylphosphine

COi is another molecule which reacts with conjugated dienes[10,95,96], COt undergoes cyclization with butadiene to give the five- and six-membered lactones 101. 102. and 103, accompanied by the carboxylic esters 104 and 105[97.98], Alkylphosphines such as tricyclohcxyl- and triisopropylphosphine are recommended as ligands. MeCN is a good solvent[99],... 

The delta lactone can be obtained in very high yields when triisopropylphosphine or tricyclohexylphosphine is the ligand along with Pd(acac)2 as the metal source (171).

Complexes of triisopropylphosphine (cone angle 160°) [69, 117]. In contrast to less bulky trialkylphosphines, a complex RhCl3(PPr3)3 has only been made by reaction at 0°C at higher temperatures, hydrides like RhHCl2(PPr 3)2 result (the less bulky tri(n-propyl)phosphine gives the 3 1 complex at reflux). 

Reaction of RhCl3 and sodium amalgam with triisopropylphosphine under a hydrogen atmosphere yields a distorted square planar complex RhH(PPr3)3 (Figure 2.66).

The interaction of triisopropylphosphine with chloroform is extremely violent, if in the absence of solvent. 

In 1979, the first isolation of the hydrido(hydroxo) complex by oxidative addition of water to an electron-rich platinum(O) complex was accomplished by Yoshida and Otsuka [22]. Highly coordinatively unsaturated bis(triisopropylphosphine)platinum (24b) can activate water very easily at room temperature to give the hydrido(hydroxo)...
