Contributions to the Chemistry of Boron, 152. 1,3,2,4-Diazaphosphaboretidines and 1,3,2,4-Diazasilaboretidines Prepared via Intra- and Intermolecular Cyclocondensation

1,3,2,4-Diazaphospha(sila)boretidines 5 and 9 are accessible via thermal decomposition of compounds of type E(NR'-BR2)2 (8) or from organoboron dihalides or boron trihalides and E(NR'Li)2 .The formation of 1,3-di-tert-butyl-4-methyl(or ethyl)-1,3,2,4-diazaphospha(sila)boretidines from the precursor E(NR'-BR2)2 proceeds by an intramolecular cyclocondensation.NMR data reveal less shielded B and P atoms in the new heterocycles as compared with noncyclic compounds; this is attributed to a strained ring system.A tetracoordinated as well as a tricoordinated boron atom is observed in CH3(O)P(NR'BR2)2 compounds resulting from intramolecular BO coordination.
