The reaction of stannylene 1 with di-tertbutylthioketene (2) gave first thiastannirane 3 as air- and moisture-sensitive crystals. X-ray analysis showed that 3 contains an acute C-Sn-S angle (45.7-degrees) and a short C-S bond (1.79 angstrom) responsible for the weakness of the Sn-C and Sn-S bonds. The reaction of 1 with thioketones 5a,b furnished thiastannolanes 8a,b via stannathiocarbonyl ylides 6 or thiastannirane 7 intermediates. Crystal data for 3: space group P2(1)2(1)2(1), Z = 4, a = 12.308 (2) angstrom, b = 14.725 (2) angstrom, c = 18.947 (2) angstrom, V = 3433.8 angstrom3, R = 0.050, R(w) = 0.064 based on 2505 reflections with \F(o)2\ greater-than-or-equal-to 3sigma\F(o)2\.
