摘要：

Enthalpies of formation of the methyl-substituted silaethylenes (CH3)nH2-nSi = CH2 (n = 1, 2) and disilenes (CH3)nH2-nSi = Si(CH3)mH2-m (n, m = 0-2) are predicted by using isodesmic reactions which relate the compound of interest to the parent silaethylene (H2Si = CH2) or disilene (H2Si = SiH2), for which accurate enthalpies of formation have recently been determined. In turn, the enthalpies of formation of these methyl-substituted compounds are used in conjunction with homodesmic reactions to reevaluate the enthalpies of formation of the silicon-substituted cyclobutenes CnSi4-nH6 (n = 0-4).
