The dichloro compounds ClB(C2H5)CC2H5=C(R)Si(CH3)2Cl : R = CH3; B: R = C(CH3)=CH2> react with Na2Se to form the five-membered cyclic compounds .A and Na2Se2 yield 1a and 3 (2). 1a is also formed from and Se in addition to (C6H5P)n and (C6H5P)4Se (5). - (3a)2 reacts with S8 to give the compounds (7a), (4)n (n = 4,5), and (C6H5P)4S (6). - 1a reacts with CH3OH under elimination of H2Se to form the intramolecularly associated (8).From 1a and acetylacetone (9) and C5H7O2B(C2H5)SeSi(CH3)2C(CH3)=CH(C2H5) (10) are obtained. 1 : 1 Adducts are synthesised from 1a or b with Lewis acids (1a-AlCl3, 1b-AlCl3) and with Lewis bases (Py-1a, Py-1b, TMP-1a). - 1a and b react thermally or photochemically with (ligand)transition metal(0) compounds or with (ligand)transition metal(I) compounds to form η4-?-complexes 4-1a, (OC)3Ru-η4-1a, Ni(η4-1a)2 (X-ray structure analysis), C5H5Co-η4-1a, (OC)3Fe-η4-1b, (OC)3Ru-η4-1b, Ni(η4-1b)2, C5H5Co-η4-1b>.The MS and NMR data (1H, 11B, 13C, 29Si, 77Se) of the new compounds are compared with those of other C2SiElB ring compounds (El = O, S, N, P).
