A Novel Synthesis of Phosphonates from Diethyl (Trichloromethyl)phosphonate
摘要:
Commercially available diethyl (1,1,1-trichloromethyl)phosphonate was reacted with aldehydes and ketones to generate (chlorovinyl)phosphonates in a single step. These intermediates could be hydrogenated in high yields to the corresponding saturated phosphonates.

Organoboranes react with phosphorus-containing carbenoids to produce a variety of functionalized organophosphorus compounds under mild conditions. In some cases, selective migration of one group attached to boron can be observed. Phosphonite-borane complexes are introduced as novel synthons for the synthesis of phosphinic esters.

The treatment of benzyl dialkylphosphites and dithiophosphites with benzeneselanyl chloride generates an Arbuzov-type transformation leading to the dialkyl selenophosphates 19a and 19b and to selenophosphorodithioates 21a and 21b. Interaction of these substrates with Lawesson's reagent yields the corresponding selenophosphorothioates 20a and 20b and the selenophosphorotrithioates 22a and 22b. When

A CuI-catalyzed cross-coupling of alkyl- and phosphorus-centered radicals for C(sp3)–P bondformation is introduced. Diacyl peroxides, generated in situ from aliphatic acids and H2O2, serve as a source for alkyl radicals and also an initiator for the generation of phosphorus radicals from H–P(O) compounds.
介绍了一种 Cu I催化的以烷基和磷为中心的自由基的交叉偶联,以形成 C(sp 3 )-P 键。由脂肪酸和 H 2 O 2原位生成的二酰基过氧化物可作为烷基自由基的来源,也是从 H-P(O) 化合物生成磷自由基的引发剂。
