1,4-CYCLOADDITION REACTIONS OF SULFUR-CON TAINING AND OXYGEN-CONTAINING CYCLIC GERMYLENES WITH 1,3-HETEROBUTADIENES CONTAINING SILICON OR GERMANIUM AND WITH 3,5-DI-T-BUTYLORTHOQUINONE
C. Laurent et al., 1,4-CYCLOADDITION REACTIONS OF SULFUR-CON TAINING AND OXYGEN-CONTAINING CYCLIC GERMYLENES WITH 1,3-HETEROBUTADIENES CONTAINING SILICON OR GERMANIUM AND WITH 3,5-DI-T-BUTYLORTHOQUINONE, Journal of organometallic chemistry, 452(1-2), 1993, pp. 41-45
Cycloaddition reactions of 1,2-dithiolane or 1,2-oxathiolanegermanediy
ls with 3,4-bis(methylene)sila- and germacycloalkanes are reported. Si
milarly, 3,5-di t-butylorthoquinone undergoes 1,4-cycloaddition with t
hese heterocyclic germylenes. The reactivity of some new dimetalapenta
lenes with bromine or dichlorodicyanoquinone (DDQ) is also described.
