- W2124088229 abstract "The detailed syntheses of a series of substituted bis(silirane)s (Me 4 C 2 SiR) 2 {R = Me ( 1a ), Ph ( 1b ), tert -butyl ( 1c )} are reported. The tert -butyl derivative ( 1c ) shows steric congestion which results in conformational rigidity in solution with respect to Si–Si bond rotation. This contrasts with the methyl ( 1a ) and phenyl ( 1b ) analogs. The rotational barriers of all three bis(silirane)s were examined by Density Functional Theory (DFT) at the B3LYP/6-31G∗ level. The calculated rotational barriers were 4.1 and 4.7 kcal/mol for 1a and 1b , respectively, but significantly higher for 1c , 29.9 kcal/mol. The thermolysis of 1c at 145 °C in the presence of bis(trimethylsilyl)acetylene gave 1,4-di- tert -butyl-2,2,3,3-tetramethyl-5,6-bis(trimethylsilyl)-1,4-disilabicyclo[2.2.0]hex-5-ene ( A ) resulting from the [2 + 2] cycloaddition of bis(trimethylsilyl)acetylene with a 1,2-disilacyclobut-1-ene intermediate ( B ). The 1,2-disilacyclobut-1-ene ( B ) presumably originates from the rearrangement of a transient siliranylsilylene produced by loss of tetramethylethylene from 1c . Purification of the 1,4-disilabicyclo[2.2.0]hex-5-ene ( A ) by column chromatography resulted in its reaction with air to afford a stable 1,4-di- tert -butyl-2,2,3,3-tetramethyl-5,6-bis(trimethylsilyl)-7-oxa-1,4-disilabicyclo[2.2.1]hept-5-ene ( C ).
