Calcium β-diketiminate hexamethyldisilazide complex catalyzes anti-Markovnikov addn. of by HPPh2 to alkenes and alkynes, affording alkyl- and alkenyldiphenylphosphines with high yields. Reaction of RCH:CH2 with HPPh2 catalyzed by calcium diketiminate [[HC(CMe:NAr)2]Ca[N(SiMe3)2](THF)] (1) gave phosphines RCH2CH2PPh2 (R = Ph, CMe:CH2), hydrophosphination of 1,3-cyclohexadiene yielded the 3-cyclohexenyldiphenylphosphine, hydrophosphination of PhC≡CPh gave (E,Z)-mixt. of Ph2PCPh:CHPh; the yields were generally above 90%. The possible intermediate, calcium diketiminate phosphide [[HC(CMe:NAr)2]Ca(PPh2)(THF)] (3) was prepd. and characterized by x-ray structural detn. [on SciFinder(R)]
Crimmin MR, Barrett AGM, Hill MS, et al., 2007, Bis(diphenylphosphido) derivatives of the heavier group 2 elements, Inorg Chem, Vol: 46, Pages: 10410-5, ISSN: 0020-1669
A number of heavier alkaline-earth (Ae) diphenylphosphides have been prepared by protonolysis of the corresponding bis(trimethylsilyl)amides and completely characterized in the solid state and in solution. Through careful control of the reaction and workup conditions, preparations performed with tetrahydrofuran (THF) as the only donor solvent crystallize as octahedral tetrakis-solvated THF adducts [Ae(PPh2)2(THF)4] when Ae=Ca and Sr. Both structures are similar and contain the two diphenylphosphide substituents in a trans disposition. In contrast, the analogous reaction performed upon the barium amide yielded a one-dimensional polymeric complex containing both five- and six-coordinated Ba centers in which the polymer is propagated via bridging diphenylphosphide units. Further strictly mononuclear derivatives of the Ca and Ba diphenylphosphides may be straightforwardly prepared by treatment of the THF adducts with 18-crown-6. Although the THF-solvated species are evidently labile to loss of solute, solution (diffusion-ordered spectroscopy NMR, THF-d8) studies indicate that, under catalytically relevant conditions, a similar mononuclear constitution is most likely retained.[on SciFinder (R)]

Homoleptic heavier alk. earth amides, M{N(SiMe3)2}2(THF)2 (M = Ca, Sr, and Ba) are reported as precatalysts for the dimerization of aldehydes to the analogous carboxylic esters (Tishchenko reaction). [on SciFinder(R)]
