Abstract:
The synthesis of two ethylene-bridged bidentate phosphines is described. 1,2-Bis(1-phospholano)ethane ((C(4)H(8))PCH(2)CH(2)P(C(4)H(8))) was synthesized by the stepwise addition of 2,2-dioxo-1,3,2-dioxathiepane to H(2)PCH(2)CH(2)PH(2). 1,2-Bis(1-phosphorinano)ethane ((C(5)H(10))PCH(2)CH(2)P(C(5)H(10))) was synthesized by the novel photochemical addition of 1,4-pentadiene to H(2)PCH(2)CH(2)PH(2). These bis(phosphines) form two-to-one complexes of the form Fe(PP)(2)Cl(2) when added to iron(II) chloride.

Aldehydes and Ketones to Alkenes: Wittig Reaction Mechanism
The reaction begins with the nucleophilic addition between a phosphorus ylide and the carbonyl compound. Due to its carbanionic character, phosphorus ylide acts as a strong nucleophile and attacks the electrophilic carbonyl group. This generates a charge-separated dipolar intermediate called betaine. The negatively charged oxygen atom and...
