Chlorobis phosphine

Example 34 bis(iV,iSr-diisopropylamino)trimethylsiloxyphosphine was prepared from readily available chlorobis(diisopropylamino)phosphine in almost quantitative yield [67]. Michalski et al. have observed that this trimethylsilyloxy-bis-(diisopropylamino)phosphine has the ability to undergo highly selective nucleophilic substitution at the atom without affecting the silicon centre. A number of 3, 5 -dinucleoside trimethylsilylphos-phites have been prepared in this way in very high yield without isolation of the mononucleotide intermediate. [Pg.120]

When chlorodiorganophosphines react with magnesium butadiene163, 3,4-bis(diorganophos-phino)-l-butenes 2 are obtained. For example, reaction of chlorobis(menthyl)phosphine gives 3,4-bis[bis(menthyl)phosphino]-l-butene in 52% total yield, but with only 16% de16. [Pg.1209]

Among other bases, DBU was applied unsuccessfully for the dehydrochlorination of chloro(dimesitylmethyl)mesitylphospine and chlorobis-(dimesitylmethyl)phosphine in tetrahydrofuran. When chloro(dimesityl-methyl)-mesitylphospine was heated with DBU in toluene, dimesitylmethane and an unidentified product resulted. [Pg.116]

From the remaining residue all volatile products are removed in vacuo at 50°/0.04 mbar followed by extraction with 4 x 100 mL of petroleum (bp 40/60). The petroleum and other volatile materials are stripped off in vacuo (0.04 mbar) at 20-50°. Almost pure (95%) chlorobis-[(dichlorophosphino)methyl]phosphine is left behind. Yield 21-30 g (5.4-7.7%).

We have also studied a further ruthenium-containing series of complexes with a different ligand set, namely chlorobis(bidentate phosphine)ruthenium alkynyl complexes, the results from which are summarized in Table 4, and efficient examples illustrated in Figure 8. [Pg.549]

The alkynyl ligands that were coupled to the nickel, gold, and cyclopentadi-enylbis(triphenylphosphine)ruthenlum centres described above were also attached to the chlorobis(bidentate phosphine)ruthenium moiety, with a similar outcome in relative quadratic NLO merit upon alkynyl ligand variation.
