peri-Interactions in Naphthalenes, 7 [1]. A Hetera-naphthalene as a Model Compound for 8-Dimethylamino- naphth-1-yl Silicon and Phosphorus Compounds

چکیده
In a 4-isopropyl-1-oxa-3-oxonia-2-borata-naphthalene the isopropyl group exhibits the same conformational phenomena as the Me2N group in 8-dimethylamino-naphth-1-yl-silanes and related phosphorus compounds. Since the details can be fully rationalized on the basis of the steric situation and electronic factors are excluded, the common features cannot serve to infer dative interaction from nitrogen to silicon / phosphorus resulting in hypercoordination of the third period element atoms in the reference compounds.

Sterically crowded peri-substituted naphthalene phosphines and their PV derivatives.
Three sterically crowded peri-substituted naphthalene phosphines, Nap[PPh(2)][ER] (Nap=naphthalene-1,8-diyl; ER=SEt, SPh, SePh) 1-3, which contain phosphorus and chalcogen functional groups at the peri positions have been prepared. Each phosphine reacts to form a complete series of P(V) chalcogenides Nap[P(E')(Ph(2))(ER)] (E'=O, S, Se). The novel compounds were fully characterised by using X-ra...
