The vegetative cell cycle of S. cerevisiae has received extensive attention. There are many justifications for this. Firstly, the cell cycle in this organism has many convenient landmarks (Hartwell 1974, 1978 Pringle 1978) which make it very easy to identify the exact point in the cell cycle at which a cell happens to be. Examples of these landmark events include bud emergence, the size of the bud, mitosis (nuclear division takes place through the neck between the mother cell and the bud), and cell...

Although a wide variety of metals were claimed as active catalysts for formaldehyde hydrophosphination, platinum salts were preferred. Similarly, Group 10 metal salts were used to catalyze acrylonitrile hydrophosphination. Russian workers showed that Ni(II) or Co(II) salts in the presence of ammonia or amines would also catalyze the addition of phosphine to formaldehyde [6]. More recently, academic and industrial interest in these reactions was sparked by a series of papers by Pringle, who investigated late metal phosphine complexes as hydrophosphination catalysts. These and related studies are arranged below by substrate. 

Pringle found that zerovalent metal complexes were active catalysts (Scheme 5-3) for the addition of PH3 to formaldehyde (see also Scheme 5-2, Eq. 1). 

Pringle proposed a general mechanism for the reaction catalyzed by zerovalent Pt,... 

Pringle showed that Ptb3 [L = P(CH2CH2CN)3] catalyzes the addition of PH3 to acrylonitrile to afford the tertiary phosphine P(CH2CH2CN)3, along with the secondary and primary phosphines PH(CH2CH2CN)2 and PH2(CH2CH2CN) (Scheme 5-4, Eq. 

The acrylate complex 10 was suggested to be the major solution species during catalysis, since the equilibrium in Scheme 5-11, Eq. (2) lies to the right (fQq > 100)-Phosphine exchange at Pt was observed by NMR, but no evidence for four-coordinate PtL, was obtained. These observations help to explain why the excess of phosphine present (both products and starting materials) does not poison the catalyst. Pringle proposed a mechanism similar to that for formaldehyde and acrylonitrile hydrophosphination, involving P-H oxidative addition, insertion of olefin into the M-H bond, and P-C reductive elimination (as in Schemes 5-3 and 5-5) [11,12].
