ORGANOPHOSPHORUS CHEMISTRY, 21. THE BEHAVIOUR OF 1-DICYANOMETHYLENE-ACENAPHTHEN-2-ONE AND 1-DICYANOMETHYLENE-3-INDANONE TOWARD ATTACK BY ALKYL PHOSPHITES

Trialkylphosphites (1a-c) and dialkyl phosphonates (11a-c) attacked 1-dicyanomethylene-acenaphthen-2-one (9) at the α-carbon atom with respect to the nitrile group, to give phosphonate adducts 13a-c and 14a-c, respectively.The reaction proceeded according to 1:2 addition.On the other hand, 1 reacts with 1-dicyanomethylene-3-indanone (10) to give the respective O-alkylated products 17, while 11 attacked 10 at the β-carbon atom with respect to the nitrile group to give the corresponding phosphonates 18.Structures of the new compounds were confirmed on the basis of elemental analyses and spectral studies.
